Computers
almost universally use the RGB color model, often
refered to as 'additive color'. That's because it's a very good,
logical model for representing color and happens to map to human vision
very well.
Artists, however, are often more familiar with the notion of Red,
Yellow and Blue as primary colors. While not perfect, this model
represents a simple method for mixing opaque medias that can represent
most colors in the spectrum. Many people consider this model to
be
completely wrong, but it is still taught in many schools as the primary
color model.
Therefore I've added a new color picker - the RYB picker. To my
knowledge, it's the only one available for a paint programs (I could be
wrong, but I couldn't find one)
The model represents Red, Yellow, and Blue as the primary colors, and
Orange, Green, and violet as the secondary colors. This
sounds odd if you're used to RGB/CYM.
There are significant issues involved in the use of this model.
For
example, Complementary colors (colors
on oposite sides of the color wheel) are completely different between
the two models. (Remember when your preschool teacher used to
tell you that red and green were oposite colors) |

Also
note
that the RYB model does not represent cyans or
magentas very well, since they are neither primary or secondary colors,
and even getting close requires the addition of white, so the
saturation level is wrong.
On a similar note, have you ever wondered why you can't mix blue and
yellow on the canvass of a paint program to get a good quality
green?
That's because in the RGB model, blue and yellow are
exactly complementary (that means an exact mix between them equals
grey).
Teachers often teach that blending complementary colors produces
grey, however in the RYB model, you actually get closer to a
brown. There are quite a few things in this model that don't
really
work the way they're supposed to. Hence, why a lot of people say
it's
wrong.
Anyway, it's what a lot of people are familiar with, so I present it
here. It was quite a hassle to get it to work, since it's not
mathmatically sound. I had to use a lookup table to produce the
actual
hues.
I didn't bother 'faking' a grey value as an 'in-between' for
complementary colors either. Still, it's a pretty
good match for the real thing.
