It would be nice to explicitly mention linear RGB space. Most
users[citation needed] these days are accustomed to colors specified
in sRGB space and naïve conversion dividing by 255 will not give the
desired blends. As an example, linear mixing black (0 0 0) with white
(1 1 1) yields (0.5 0.5 0.5). Naïve scaling will yield #808080 whereas
middle gray is somewhere around #bebebe in sRGB.
