Sorry for the noise.
I think I’m too tired...
there is an alternative interface on top of the existing one (coming) ...
% maybe handy:
definecolor [ name = "MyColor3", r = 0.22, g = 0.44, b = 0.66 ] ;
definecolor [ name = "MyColor4", r = 0.66, g = 0.44, b = 0.22 ] ;
% parameter driven:
draw lmt_shade [
path = fullcircle scaled 4cm,
direction = "right",
domain= { 0, 2 },
colors= { "MyColor3", "MyColor4" },
] ;
but tweaking shades will never be easy

[NTG-context] colors in MetaPost
Hi,
I’m trying to get a linear shade in the background of my presentation.
But it seems like MetaPost can’t handle my self-defined colors:
\definecolor[VerlaufVon][c=75,m=5,y=95,k=60]
\definecolor[VerlaufNach][c=88,m=95,y=5,k=60]
\startuniqueMPgraphic{Verlauf}
% old method, also doesn’t work
% path p ;
% p := unitsquare xscaled \overlaywidth yscaled \overlayheight ;
% linear_shade(p,6,\MPcolor{VerlaufVon},\MPcolor{VerlaufNach}) ;
fill fullsquare xyscaled (\overlaywidth,\overlayheight)
withshademethod "linear"
withshadevector (0.5,2.5)
%withshadedirection shadedup
withshadecolors ("VerlaufVon", "VerlaufNach")
;
\stopuniqueMPgraphic
\defineoverlay[verlaufen][\useMPgraphic{Verlauf}]
\setupbackgrounds[paper][background={verlaufen}]
\starttext
\strut
\stoptext
The background consists of a blue and a green area instead of a shade. While
testing I sometimes got a few more stripes in the top and bottom area, can’t
reproduce any more.
I also tried RGB and hex (HTML) definitions. Predefined colors work.
According to the MetaFun manual, either \MPcolor{name} or just "name" should
work.
What’s wrong?
Greetlings, Hraban

AFAIR, I splitted the caches because they were different and I checked this again: I deleted TEXMFCACHE directories (lmtx and context-suite ones), regenerated both using $ mtxrun --generate; context --make (using the right mtxrun, /usr/local/opt/context/tex/texmf-linux-64/bin/mtxrun and /usr/local/opt/lmtx/tex/texmf-linux-64/bin/mtxrun in my case) and checked the generated files.
