Hi, the following does not seem to use color. Am
I missing something? Never used this feature
before...
I use mkiv with luatex 0.36.
\startMPcode
draw thelabel(btex RED etex, (0,0)) withcolor blue;
\stopMPcode
\stoptext
Thanks, Eythan

I think what Wolfgang meant was
label(textext("\red RED"), origin)

Wolfgang
Basically, you moved it to TeX to do the coloring,
which is ok.
Now, "draw thelabel(btex RED etex, (0,0)) scaled 2;" works.
In the same manner , I think,
"withcolor" should work. At least this is my
understanding of the manual. But instead it is
silently ignored. So my question is whether it
is a bug or not.
This may not be a context's issue but a metapost's itself.
Thanks, Eythan

Metapost in MkIV is different from MkII and all labels are typeset
and colored in TeX, if you want a label use textext(...).
My \textext{...} (which is only defined in MkII) is just a TeX
wrapper and converts \textext{\blue RED} in textext("\blue RED")
and in MkIV btex ... etex is converted in textext(...) too.

What's written in the manual should work in MkII but a lot
of things are handled in a different like colors.

indeed tex does the coloring; also honoring mp's colors has been
discussed on this list but fo rthe moment will nto be supported as it
will complicate the code; maybe when i have redone the backend and when
multiple pre/postscripts are supported (on the mplib agenda)
