| Some of the confusion about color wheels comes from the
fact that there are two different types of color wheels. One is known as
additive, the other subtractive. The light you see in a rainbow, the light
you see all-round you, is additive. The Primary colors for additive color
wheel are Red, Green and Dark Blue- when added together you get white. If
you are a photographer you need to understand the principals of additive
color wheels, as a painter you would do best just to forget all that; for
the time being anyway. The painters color wheel is what most of us learned
in school, where Yellow, Red, and Blue are the primaries, when added
together you get brown muck. The secondary colors are Orange, Purple,
and Green. IF you are into exploring more about both color wheels and understating
a little about both additive and subtractive I recommend

Theory Too Once you learn the basics of the color wheel,
all in theory, and you begin to put it into practice, you run into a few
problems.
First and foremost - pigments. If all there
was to color you could learn from a color wheel mastering color theory
would be a snap. First you must understand the difference between
pigments. How the pigment is arrived at. Animal, vegetable or
mineral/ each has a different base and will react differently. Some will
never give an intense hue, some are heavy with chalk which makes for a
gritty paste in transparent watercolor and mixing problems for
other media and so on. This brings up the next point. Some
consideration to the binder, or medium must be observed. For
instance, it is generally assumed in oil and acrylic paints that you can
mix black with yellow to get green. I don't suggest you do this
with transparent watercolor, you wouldn't like it. Thirdly you must differentiate
between paint companies, how they manufacture their paints, what they
put into them, how the binders will effect the final outcome of the
color you intend or thought you were going to have on your painting.
Some pigments vary slightly by grade. Now there is a large number of
artificial (man made) pigments that are considered just as good and not
as toxic, by the industry.
