I see that you were trying to change the color of a Chapter Heading, in
particular. This does seem like a mess, easily reproducible by me; titles and sections seem to work, though. Evidently a problem for the masters.
The reason, as Jurgen pointed out, is because the chapter headings turn
up in the page headers---not to mention the TOC. So you really don't
want to change its color anyway, not manually. If you want chapter
headings to be colored, you change that in the document class.
