Hi all, I understand that in order to use a color with \color[somecolor]{colored text} I first have to \definecolor[somecolor][r=.4,g=0,b=1]. Currently I'm trying to do automated colorizing with the help of some lua code and I'd like to make up rgb vectors on the spot without having to \definecolor them first, e.g. something like \color[r=.4,g=0,b=1] {colored text}. Is there a way to achieve this in mkiv? (Right now I'm assigning new rgb values to the same color "name" whenever the function is called that concatenates the next \color[]{} statement. This seems a bit verbose and hacky to me.) Thanks in advance, Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

\colored[r=...,g=...,b=...]{...} or {\colored[r=...,g=...,b=...]...} Wolfgang

No, \colored is \definecolor + \color except you can use it in the form \colored[rgb]{...} and {\colored[rgb]...} while \color can only be used as \color[rgb]{...}. Wolfgang

No. Both \color[rgb]{...} and {\color[rgb]...} are valid \definecolor[myred][r=0.65] \starttext {normal text \color[myred]{red text} normal text} {normal text {\color[myred]red text} normal text} \stoptext Aditya

\colored is a rather recent command. Mojca

I meant the manuals and wiki mention \color[name]{...} but not the form {\color[...]...}. Wolfgang

But used \color always \groupedcommand or was this added later and the original definition was what is mentioned in the manual (\color[]{})? Wolfgang

it's a very old command so it might not have used groupedcommand in the past also, at the time of manual writing no groupedcommand like things were there anyway but .. there's another reason ... \color{...} does not grab an argument but does some aftergroup trickery so it might not work in all cases also in mkii we inject literals and we could end up with dangling revert color cases being nodes that could interfere somehow mkiv is more robust ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
