Additive versus Subtractive
Primary colors can be categorized as either additive or subtractive.
Computer monitors use additive primaries.
The printing process uses subtractive primaries.
How do the two differ?
Additive Primaries
The additive primaries are Red, Green and Blue (RGB). Video technology such as computer
monitors and television screens uses additive primaries.
Starting from black (lack of color) and adding red, green and blue in equal quantities will
generate shades of gray. A full, balanced mixture of all three colors produces white. Mixing the
three colors in different quantities will generate intermediate colors.
