\Command{\tex{setupcolors}}
\Command{\tex{color}}
\Command{\tex{definecolor}}
Text, frames or backgrounds can be set in color with:
\shortsetup{color}
Default the basic colors are available. Basic colors are for example
red, white and blue. A color like orange can be defined with:
\shortsetup{definecolor}
You can define orange like this:
\startbuffer[a]
\definecolor [darkorange] [c=0.0,m=0.60,y=1.00,k=0.0]
\definecolor [middleorange] [.5(darkorange)]
\stopbuffer
\typebuffer[a]
\getbuffer[a]
It is of good practice to check (combinations of) colors on a larger
surface:
\startbuffer
\blackrule[width=\hsize,height=1cm,color=red,after=]
\blackrule[width=\hsize,height=1cm,color=white,after=]
\blackrule[width=\hsize,height=1cm,color=blue,after=]
\blackrule[width=\hsize,height=1cm,color=darkorange]
\stopbuffer
\typebuffer
so you can see if they fit together:
\blank
\getbuffer
A color can be invoked in a number of ways:
\startbuffer
\startcolor[red]
On {\darkorange Kingsday} {\blue Hasselt} turns into a
\color[darkorange]{colorfull} city.
\stopcolor
\stopbuffer
\typebuffer
\getbuffer
More information on the use of color models, transparency and palets can be found
on the \goto {\CONTEXTWIKI} [ url (http://wiki.contextgarden.net/Color) ]
and in the
\goto {\em Color Separation} [ url (manual:color) ] manual.
