The first mistake most people make when computer coloring

The first mistake (there are two!) that people make when computer coloring is.... 

Tolerance!

When people start coloring their line art in Photoshop, they don't realize that the computer is acting mathematically, and it is finding areas to color based on math settings that WE give it.

If our settings (a "tolerance" number between 0-255) is too small, the odds are that our art will have a little light-colored or white line before the line once we color it. 

Below is a selection set to "10" which is then colored with red. See the little inner "halo"?

But below, it's set to 100. 

See how that selection area is farther into the black line work? That will get the color in there a little better...

Much better!

So what is tolerance? It's looking for a greyscale value (how light or dark) to know where to STOP. 0 is stop at anything, 255 is stop at nothing, and all the numbers in between are there for you to play with!

Next time we'll tell you about TRAPPING.
