Hi,
It seems to work when defining a color as described in
https://wiki.contextgarden.net/Color_in_MetaPost , if that's an option:
________________________________________________
\startMPcode
color MyColor ;
MyColor = (.5, .25, .25) ;
fill fullsquare xyscaled (40mm, 15mm) withcolor MyColor ;
fill fullsquare xyscaled (40mm, 15mm) shifted (42mm, 0mm) withcolor
0.5MyColor ;
\stopMPcode
________________________________________________
Otherwise the solution proposed by Hans is probably better. (And may well
be better anyway!)
Cheers,
Florent

with the environment of
\startMPcode you can scale a color with a factor like 0.25red and 0.5blue
But this not seem to work when you define a color yourself first
definecolor [ name = "MyColor", r = .5, g = .25, b = .25 ] ; fill fullsquare xyscaled (40mm, 15mm) withcolor "MyColor" ;
fill fullsquare xyscaled (40mm, 15mm) shifted (42mm, 0mm) withcolor 0.5"MyColor" ;
What would be the correct way to scale self defined colors?
