Hi Hans I don't know if the latest beta already has the new code. But I can confirm, that there is still a difference between tikz-colors and context/metafun colors.
TikZ translates c=1,m=1 in (native) RGB, that is b=1, which is in some way correct. ConTeXt translates c=1,m=1 in something I couldn't really define (perhaps sRGB or some other color profile) r=0.183... g=0.191... b=0.574... or in Web-Hex: #2e3092 or back to cmyk: c=.68, m=.67,k=.43 (which is blue with some key-value compared to TikZ with k=0) So I think that TikZ and ConTeXt don't use the same color profile.... Hope it could help somewhat to solve my problem.
