Coloring and Shading;
Okay, now that we've covered how to draw the lines, let's color them in.
Here's a simple circle I've colored and filled with block shading
Nothing to special, badly blended. How can we fix that? Well, with a technique called "Dithering". Here's the circle shaded with dithering
Doesn't that look so much better? The colors blend better, look as if they're a gradient. Now, there are many ways to dither, no one way is the right way. It all boils down to what you're comfortable with. Not all shading situations need dithering either.
There's bases for example:
No dithering was used in these examples. Find what's comfortable for you and experiment.
Now, when coloring and shading, be careful with what colors you use.
You don't want to use colors that are TOO saturated, or not saturated enough.
Here's an example of TOO saturated:
See how it's kind of painful to look at.
Also remember to use different colors. Nothing is just green or blue, but a mix of lots of colors.
See as some of the colors get darker or lighter, the color also change slightly. From green to yellow or purple to blue, when working with color, remember color theory. This will lead to a more appealing color scheme.
