The main problem was that one had to intercept the string (the
terminal gives the same output for all "marks"). The hint that you
gave me an hour ago lead me to the following solution that seems to
work OK:
vardef [EMAIL PROTECTED](expr txt) =
let,=@;
save r, g, b;
r = redpart gp_color_current;
g = greenpart gp_color_current;
b = bluepart gp_color_current;
rawtextext("\colored[r=" & decimal(r) & ",g=" & decimal(g) & ",b=" &
decimal(b) & "]{" & txt & "}")
enddef ;
Writing the string \colored[...] directly would need heavy
modifications in the terminal. Now this hack works really nice.

But that requires modifications to terminal again & incompatibility
with output between engines. I'll try to figure out how to do
something similar as above. I would like to write this as
\sometxt[gp][iwona,20pt]{The Title}. I "just" need to redefine the
meaning of \sometxt somehow.

I thought that was planned for 2068? (At least that was what Ton said,
or rather sang.)
