The RGB mixing creates brighter colors, while the CMYK mixing results in darker colors. Fundamentally different modes of mixing. Which conjunctions will make the distinction in tanru? "lo xunre joi crino cu pelxu" may be true in RGB but not in CMYK; "lo pelxu joi nukni cu xunre" may be true in CMYK but not in RGB. The Venn diagrams for these color models seem to hint at sets as much as masses -- the sort of "jo'e" (union) as well as "joi" (mixed mass). But we can't really say that "xunre jo'e crino" is additive and "pelxu jo'enai nukni" subtractive in the particular sense of physical color combination, can we? mu'o -- You received this message because you are subscribed to the Google Groups "lojban" group.
