Subtractive (colour) process
Method of reproducing colours in which white light passes successively through two or more images, each dyed in a colour which absorbs (subtracts) a region of the visible spectrum transmitted by the others.
The colour produced depends upon the quantity of light absorbed by each dye. The colour dyes — cyan, magenta and yellow — are used. These are often termed minus red, minus green and minus blue since they absorb the colours red, green and blue respectively.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
