Secondary Colors: The Complete Guide

The three secondary colors are orange, green, and purple. You get them by mixing two primary colors in equal parts. Red and yellow make orange. Blue and yellow make green. Red and blue make purple.

That’s the short answer. But if you have ever mixed red and blue and ended up with a sad gray-brown instead of purple, you already know the short answer is not the whole story.

This guide covers what secondary colors are, how to mix each one properly, why the mixes sometimes go wrong, and how the same idea works on screens and in print. Every color comes with a hex code so you can use it anywhere.

What is a secondary color?

A secondary color is any color made by mixing two primary colors together. Primary colors are the starting point. Secondary colors are the first step away from them.

The name tells you the order. Primaries come first. Secondaries come second. Mix a secondary with a primary and you get a tertiary color, the third level.

On the color wheel, each secondary color sits exactly halfway between the two primaries that create it. Orange sits between red and yellow. Green sits between yellow and blue. Purple sits between blue and red. The position is the recipe.

The three secondary colors

Secondary color	Made from	Hex code
Orange	Red + Yellow	#FB9902
Green	Yellow + Blue	#66B032
Purple (violet)	Red + Blue	#8601AF

Simple on paper. In real paint, each of these three mixes behaves a little differently. Let’s take them one at a time.

Orange: the easy one

Orange is the most forgiving mix in painting. Almost any red plus almost any yellow gives you a usable orange.

The reason is simple. Red and yellow sit close together on the warm side of the wheel. They share a lot of common ground, so their mix stays clean and bright.

Start with yellow and add red little by little, not the other way around. Red is a much stronger pigment. A few drops shift the mix fast, while yellow needs a lot of paint to fight back.

Want a deeper, burnt orange? Add a tiny touch of blue or brown. Want a soft peach? Add white. The full set of recipes and shades is in our guide on what colors make orange.

Green: the flexible one

Green gives you the widest range of results of any secondary mix. Change the ratio a little and you slide from bright spring green to deep forest green.

More yellow gives you lively, grassy greens. More blue gives you cool, dark greens. Equal parts lands in the middle, a solid true green around #66B032.

The choice of blue matters a lot here. A green-leaning blue like cerulean makes clean, vivid greens. A violet-leaning blue like ultramarine makes duller, more natural greens. Both are useful. It depends on what you are painting.

Nature is mostly muted greens, not bright ones. So if your landscape greens look fake, mute them with a small touch of red. Every version is covered in what colors make green.

Purple: the tricky one

Purple is the mix that breaks the rule. Red plus blue should make purple. Often it makes mud instead.

Here is why. Most reds secretly lean toward orange, and orange contains yellow. So when you mix that red with blue, you are really mixing all three primaries at once. Three primaries together always make brown or gray.

The fix is to pick the right tubes. Use a red that leans toward violet, like alizarin crimson. Use a blue that leans toward violet too, like ultramarine. Now both paints are already pointing at purple, and the mix comes out clean.

This one trick saves more beginner paintings than any other. The complete walkthrough, with shades from lavender to plum, is in what colors make purple.

Why “equal parts” is only a starting point

Every textbook says to mix two primaries in equal amounts. Treat that as a starting point, not a law.

Pigments have different strengths. A strong pigment like phthalo blue can overpower a weak one at a 10-to-1 ratio. Equal amounts of paint does not mean equal amounts of color.

So work like a cook, not a chemist. Start with the lighter, weaker color. Add the stronger color in small steps. Stop when the mix looks right, not when the amounts look even.

And keep notes. When a mix works, write down roughly what went in. Your notes become your personal recipe book, and they are worth more than any chart.

How to lighten, darken, and mute each one

The three secondaries at full strength are loud. Most real projects need softer versions. There are three moves, and they work on every color.

Add white to lighten. This makes a tint. Orange becomes peach. Green becomes mint. Purple becomes lavender.

Add black (or better, the complement) to darken. This makes a shade. Orange becomes rust. Green becomes forest. Purple becomes plum. Go easy with black, because it can deaden a color fast.

Add gray to mute. This makes a tone. Toned colors are calmer and easier to live with, which is why interior paint charts are full of them.

Base	Lighter (tint)	Darker (shade)	Muted (tone)
Orange #FB9902	Peach #FDC97F	Rust #9E5F00	Clay #C08A4D
Green #66B032	Mint #A8D68E	Forest #3B6B1D	Sage #7D9A66
Purple #8601AF	Lavender #BE8FD6	Plum #4C0763	Mauve #8A6699

Secondary colors on the color wheel

Look at the finished wheel and a neat pattern shows up. Every secondary color sits directly opposite a primary color.

Orange faces blue. Green faces red. Purple faces yellow.

Colors that face each other are called complementary colors, and the pairing is useful in two opposite ways. Side by side, a secondary and its complement make each other look brighter. That is why orange pops so hard against blue. Mixed together, they cancel each other out into a neutral. That is how painters tone down a color without black.

So the wheel gives every secondary color a built-in partner and a built-in off switch. Once you see it, you use it constantly.

Secondary colors in light: RGB

Everything above is about paint. Screens play by different rules.

Your phone and TV mix light, not pigment. The primary colors of light are red, green, and blue. Notice that green got promoted. In light, green is a primary, not a secondary.

The secondary colors of light are the surprising part. Red plus green light makes yellow. Green plus blue light makes cyan. Red plus blue light makes magenta.

So in the RGB world, the secondaries are cyan #00FFFF, magenta #FF00FF, and yellow #FFFF00. Light also adds up instead of down. Mix all three light primaries and you get white, not brown. Our short guide on what RGB is explains how screens pull this off.

Secondary colors in print: CMYK

Printers flip things one more time. Printing ink is subtractive like paint, but it uses smarter primaries: cyan, magenta, and yellow.

Mix those inks in pairs and the secondaries turn out to be old friends. Magenta plus yellow makes red. Cyan plus yellow makes green. Cyan plus magenta makes blue.

So red and blue, the untouchable primaries of the paint world, are just secondary colors in print. It sounds like a contradiction, but it isn’t. “Primary” and “secondary” are roles, not fixed labels. The medium decides which colors play which role. The CMYK color model guide covers the details.

The next step: tertiary colors

Secondary colors are the middle of a ladder, not the end of it.

Mix a secondary with the primary next to it and you get a tertiary color. There are six: yellow-orange, red-orange, red-violet, blue-violet, blue-green, and yellow-green. Their two-part names are literal recipes.

Add the six tertiaries to the three primaries and three secondaries and you get the full 12-color wheel that artists and designers work from. If you want the whole map in one place, the color wheel guide walks through all twelve, with hex codes.

Using secondary colors in real life

A few honest observations from how these colors get used.

Orange sells energy. It reads as friendly, urgent, and affordable. That is why sale tags, sports brands, and safety gear lean on it. Full-strength orange tires the eye fast, so use it in small doses.

Green sells calm and nature. It is the easiest secondary to live with across large areas, which is why it dominates bedrooms, banks, and anything organic. Muted greens age better than bright ones.

Purple sells rarity. For centuries the dye was so expensive that only royalty wore it, and the association stuck. Deep purples feel premium. Light purples feel gentle and creative.

One practical rule ties them together. Pick one secondary as your accent, keep it under about ten percent of the design, and let quieter colors carry the rest. A little goes a long way with all three.

A quick history of the secondary colors

The idea is older than the name. Painters in the 1600s already knew that orange, green, and purple could be mixed while red, yellow, and blue could not.

The printmaker Jacob Le Blon proved the system in 1725 by printing full-color pictures from just three ink plates. A few decades later, Moses Harris drew the first proper color wheel and placed the three secondaries between the primaries, right where they still sit today.

The word choices stuck too. “Secondary” simply meant second in order of mixing. Nothing about the name means second in importance. Green covers more of the natural world than any primary, and purple was once the most expensive color on earth.

One more historical note worth knowing. Purple dye once came from sea snails, and it took thousands of snails to color a single robe. That is the whole reason purple still reads as royal. The color’s price tag wrote its meaning.

Are secondary colors warm or cool?

The color wheel splits into a warm half and a cool half, and the three secondaries land in interesting spots.

Orange is fully warm. It sits in the middle of the warm side, between red and yellow, and there is no such thing as a cold orange. That makes it the most energetic color on the wheel.

Green and purple are the border guards. Each one has a warm version and a cool version. A yellow-leaning green feels warm and sunny. A blue-leaning green feels cool and quiet. A red-leaning purple feels warm and rich. A blue-leaning purple feels cool and calm.

This matters when you decorate or paint. Two greens can clash with each other if one is warm and one is cool. Pick a temperature and stay on that side, and rooms and paintings hold together better.

How to mix a secondary color, step by step

Here is the routine that works for all three mixes. It takes a minute longer than dumping two blobs together, and it saves paint every time.

Step 1. Check the bias of both tubes. Smear a thin streak of each on white paper. Look at the edge. Does your red lean orange or violet? Does your blue lean green or violet? Pick the pair that leans toward your target color.

Step 2. Put out the lighter color first. Yellow before red for orange. Yellow before blue for green. Red before blue for purple, since most blues overpower most reds.

Step 3. Add the stronger color in small touches. Use the tip of the brush or knife, not a scoop. Mix fully between touches. Strong pigments sneak up on you.

Step 4. Test on white before you commit. Every mix looks darker in the pile than on the surface. A quick swatch on scrap paper tells the truth.

Step 5. Adjust with the smallest move possible. Too dull? Add more of the brighter parent. Too loud? Add a whisper of the complement. Too dark? Add the lighter parent before you reach for white.

Mix each secondary this way five or six times and the routine becomes automatic. After that, you stop following recipes and start steering by eye, which is the actual goal.

Common mistakes with secondary colors

Mixing purple with the wrong red. The number one mud-maker. Check your red’s bias before you blame the ratio.

Adding the strong pigment first. Always start light, add dark. You can darken a mix forever, but you can’t easily un-darken it.

Using black to darken everything. Black flattens color. Darken orange with a touch of blue, green with a touch of red, purple with a touch of yellow. The color stays alive.

Expecting screen colors to match paint. #66B032 on your monitor and the green in your tray are cousins, not twins. Screens mix light, paint mixes pigment. Match by eye, not by code.

Using all three secondaries at full strength together. Orange, green, and purple form a triadic scheme, which can work, but at full saturation it shouts. Mute two of the three and the same scheme turns elegant.

A five-minute exercise that makes it stick

Reading about mixing is not the same as mixing. Here is the fastest way to make secondary colors second nature.

Take your three primaries and a sheet of white paper. Mix each pair three times: once with more of the first color, once equal, once with more of the second. Paint a small square of each result.

You will end up with nine squares. Three oranges, three greens, three purples, each family running from one parent toward the other.

Now look at what you made. The middle square of each row is the textbook secondary. The outer squares are already tertiary territory. In five minutes you have painted a working slice of the entire color wheel, and you understand it in your hands, not just your head.

Keep the sheet. Date it, note which tubes you used, and pin it near where you work. It will answer more mixing questions than this article ever could.
