|Color Mix||Lab Report|
The purpose of ColorMix is to provide an interactive laboratory for mixing "additive" or "subtractive" colors.
RGB (Red-Green-Blue) is an "additive" color system used in color display monitors where light is mixed. CMY (Cyan-Magenta-Yellow) and CMYK (Cyan-Magenta-Yellow-blacK) are "subtractive" color systems used in printing where inks or pigments are mixed.
This project is an interactive version of Plate III (after p. 240), "Primary and secondary colors of light and pigments," in Digital Image Processing, but note that the CMY plate has been rotated in the book's version.
Materials and Equipment
Delphi 3/4 (to recompile)
800-by-600 display in High Color or True Color Mode
Additive Colors (Mixtures of Light)
Black + Red = Red
Black + Green = Green
Black + Blue = Blue
Black + Red + Green = Yellow
Black + Red + Blue = Magenta
Black + Blue + Green = Cyan
Black + Red + Green + Blue = White
Subtractive Colors (Mixtures of Pigments)
White - Red = Cyan
White - Green = Magenta
White - Blue = Yellow
White - Red - Green = Blue
White - Red - Blue = Green
White - Blue - Green = Red
White - Red - Green - Blue = Black
Synthèse additive et soustractive (French). Similar but interesting example:
The next time you see a yellow flower, such as a tulip or a dandelion, think of the flower as being "NOT Blue" instead of "Yellow".
