A colour space defines a range of reproducible colours. EOS cameras support both sRGB and Adobe RGB colour spaces.
sRGB describes the range of colours that can be shown on a standard computer monitor or a beamer/projector.
Adobe RGB offers a broader colour palette than conventional sRGB, particularly for colours in the cyan to green and orange regions. Adobe RGB images deliver better colour rendition than sRGB when printed, but do not look as good on a monitor or beamer
as an sRGB image. As Adobe RGB has a wider colour space than sRGB, it is possible to convert Adobe RGB to sRGB with post processing.
