I have a stylesheet that works as expected in Mathematica 8. It does not work as expected in Mathematica 9.

In the stylesheet I have set FontColor to RGBColor[0.501961, 0, 0] for ItemParagraph. DisplayFormula and InlineFormula have FontColor set to Automatic (I've also tried Inherited).

When I press ctrl+( to start a formula from within an ItemParagraph the color is the same as for my Text cell (black). The FontColor option for Text is Automatic.

Interesting behavior. When I type esc+intt+esc the font color is RGBColor[0.501961, 0, 0] and it creates an inline formula region (or is it displayformula?). When I type ctrl+/ it creates an inline formula region but the color is black.

I have both Mathematica 8 and Mathematica 9 installed and the behavior does not exist on Mathematica 8.

I don't have 9 installed but there has been some discussions about the default stylesheet changing in 9. I'd guess that this change is the source of the problem. – Mike Honeychurch Dec 18 '12 at 1:00
That's certainly possibly the reason for the behavior. Any ideas on what I would change in the Defaul.nb? – YequalsX Dec 18 '12 at 1:02
Unfortunately no because I do not know what changes were made to the default style in 9. However you could try making your style sheet inherit from Default_8.nb instead of Default.nb. I believe -- stand corrected -- that in 9 Default_8.nb is the V8 default stylesheet. – Mike Honeychurch Dec 18 '12 at 1:05
fyi, to change to V8 style sheet in V9, please see mathematica.stackexchange.com/questions/15918/… – Nasser Dec 18 '12 at 2:38
I can't reproduce the behavior you described in V9. The color of the InlineFormula in an ItemParagraph cell is the same with the stylesheet setting (RGBColor[0.501961, 0, 0]). – Silvia Dec 19 '12 at 3:28

In Mathematica 8 Default.nb has the FontColor option in DisplayFormula set to Automatic. In Mathematica 9 this is set to GrayLevel[0.2]. I have not figured out a way to change this to Automatic but this is the reason for the strange behavior.

(+1) Does this work: CurrentValue[{StyleDefinitions, "DisplayFormula", "FontColor"}] = Automatic? – kguler Dec 18 '12 at 7:26
No. In the local definitions for FontColor for DisplayFormula I can set it to the color I want but this is over ridden by Default.nb. My stylesheet inherits from Default.nb. This appears to be a bug in Mathematica 9. – YequalsX Dec 18 '12 at 15:45
