First, Placement

Other things about color advice are placement and how much of what color.

First, placement

Let's take the two stickmen from above (the red and blue).

Color placement is important because it lets the viewer know what to look at.

For example, the stickman to the left is completely red. Nothing is there for our eyes to focus on. We can't get anything from this character. Except that maybe it's really angry or full of love (as red can also mean love). Meanwhile, the stickman to our right gives us something to focus on, this being it's hands, markings, and circle on its chest. This could give us the meaning that maybe they are powerful or can manipulate heat.

But, if I were to switch it up...

the color placement here is vastly different.

Now the only thing to focus on here would be the stickman's hands. It may give off the impression of heat manipulation a little stronger than the first.

But what about the blue?

The color placement on the hands makes us immediately focus on them, possibly giving off the vibe that this character is a little dangerous, compared to the blue, which some might feel more compelled to trust.

But if I switch the colors like this...

Woah. That is a stark difference.

One could get an intimidating, 'i am dangerous, don't mess with me' vibe from the new color change.

Now, the next point:

Color quantity (how much of what color)

Now... Let us focus on this new buddy.

The amount of whatever color you choose matters.

Notice the tiny amount of blue compared to the amount of black?

The amount of black is so overwhelming to the blue that it can give off the impression that this stick is dangerous and takes no shit.

But... What if I switched the amount?

Now, this character doesn't look so scary :3

The amount of one color can totally change how viewers will feel, think, or connect to your art!

But again, don't be afraid to experiment! Many people have made amazing things out of the weirdest color combos and it looks awesome. So don't be afraid to experiment. :3

Pwes gip me coloring advice o Master🙏

Color theory.

You want colors that look good with each other? Try complimentary colors, analogous colors, tri- something and all the other cool ones!

Of course, there's MANY different interpretations about how people see color, so the most important advice of all, DONT BE AFRAID TO EXPERIMENT!!! :D
