Hi,
for a batch command (ImageMagick) I need to convert ConTeXt colors to a
text representation (e.g. rgb 'red' -> 'rgb(255,0,0)'; same for color
models cmyk and gray).
What is the best way to get (read only) access to the color channels of
a defined color?
\colorcomponents{red}
\colorvalue{red}

in next beta:

\startluacode

-- inspect(attributes.colors.spec("red"))

-- table={
--  ["b"]=0,
--  ["c"]=0,
--  ["model"]="cmyk",
--  ["g"]=0,
--  ["k"]=0,
--  ["m"]=1,
--  ["r"]=1,
--  ["s"]=0.3,
--  ["y"]=1,
-- }

\stopluacode
