Unfortunately history makes things confusing. The red, blue, yellow that
people have been using for centuries are now often called magenta, cyan,
yellow. But many people still call them red, blue, yellow. They aren't
wrong to do so, but it can make color stuff confusing.
Normally the two realms don't mingle much -- computer people and
lighting people use additive color and don't have to worry about
subtractive color. Painters tend to concern themselves with only
subtractive color. Some few of us straddle both. I frequently forget
whether cyan and magenta refer to the primary blue and red lights or
pigments. Oh well. [sigh]
