Color Mixing
There has been much confusion about color
over the years, and perhaps the biggest confusion has been the
differences between mixing colored light and mixiing colored inks
or paints.

When mixing light, it is called additive color mixing. In the
photo, blue, green, and red light are mixed. Where they all intersect,
white is formed. In other words, mixing Blue, Green, and Red light
yields white light. This is how color is viewed on your computer
monitor. Red, Green, and Blue lights are combined to produce colors.

When mixing pigmented ink or paint, it
is called subtractive color mixing. By mixing Blue, Red, and Yellow
pigments together you get Black. This is how color is viewed when
you look at a Pantone book.
