Name of contribution: xcolor 1.06 Suggested location on CTAN: macros/latex/contrib/xcolor Summary description: Driver-independent color extensions for LaTeX and pdfLaTeX License type: lppl
Announcement text:
2003/12/15 v1.06
- New feature: extended color expressions, allowing for cascaded mix operations, e.g. color{red!30!green!40!blue}.
 - Documentation: new section on color expressions.
 - Bugfix: color series stepping did not work correctly within non-displaying commands like extractcolorspec{foo!!+} (this bug was introduced in v1.05).
 - Renamed commands: ukfileversion and similar internal constants renamed to XCfileversion etc.
 - Removed commands: ifXCpst and ifXCtable made obsolete by a simple trick.
 
Thanks for the update, I installed it as requested.
