Why do my colors keep turning to mud?

Has this ever happened to you?

You set out to paint beautiful, clean colors.

You start mixing...

And somehow everything turns into a dull, muddy mess.

Ugh. 🤦

Here's the funny thing:

There's really no such thing as a "bad" muddy color.

If you're painting dirt, tree bark, distant foliage or any number of muted colors in nature, that grayish mixture might be exactly what you need.

The problem is when you didn't intend to make it.

And that's where understanding a little practical color theory can save you a lot of frustration.

Let's say you're painting a late afternoon sky.

You've got blue above and orange closer to the horizon.

Blue and orange are complementary colors.

When complements are mixed together, they neutralize one another.

So if you start blending the two together without understanding what's happening, that beautiful blue-to-orange transition can quickly become...

Yep.

Mud.

But complementary colors aren't the enemy.

They're actually incredibly useful.

Let's say you've mixed a green that's much too bright for the landscape you're painting.

What does it need?

You could start randomly adding colors until something works.

Or...

If you understand the relationship between colors, you know exactly which direction to go. And you'll know how to tame that green.

That's the difference between guessing at color and controlling it.

The same thing applies when paint gets overworked on the canvas.

Every time you continue working wet colors into one another, you're changing the mixture.

Sometimes that's exactly what you want.

Sometimes it isn't.

That's one reason I prefer painting in layers. I can establish an area, let it dry, and come back to refine it without continually stirring wet colors together.

The important lesson isn't that muddy colors are bad.

It's this:

When you understand why your colors are behaving the way they are, you can make them do what you want.

And that's practical color theory in action.

Want to see another way I use color theory in practice?

Sometimes the color I've already painted is close, but it still needs to be warmer, cooler, darker or more neutral. Rather than repainting the area, I can often adjust it with a glaze.

In this video, I'll show you how I use glazing to fine-tune color in an actual landscape painting.

It's another example of practical color theory — understanding what a color needs and knowing how to get it there.

Enjoy the journey!

p.s. I’ve been doing some work behind the scenes on my color mixing course, including giving it a new name that better reflects what I actually teach. I’ll share it with you soon.
