Doing another rainbow test using styles.xml textcolor areas I was able to determine a few things of what is what.
The Lines may not be the same on your styles.xml, but their respective names should be. Keep in mind this is for CM7 based ROMS.
Line 293 widget.button - button text
Line 387 widget.edittext - status update for facebook etc.
Line 539 TextAppearance.Large.Inverse - Large text in menu for shut down etc.
Line 545 TextAppearance.Medium - Lockscreen text, and text on popups (red in pics)
Line 554 TextAppearance.Small - small text in menus (black in pic)
Line 557 TextAppearance.Small.Inverse - small text in menu for shut down etc (sound is on etc.)
Line 566 TextAppearance.Widget.IconMenu.Item - menu from desktop where settings etc is (purple)
Line 591 TextAppearance.Widget.DropDown.Item text next to radio buttons in ADW, but not rest of CM7, contact dropdown in sms
Line 594 TextAppearance.Widget.TextView.SpinnerItem choose text in dropdown box (the 2nd one)
Line 599 TextAppearance.WindowTitle word on top "settings" "app name" etc. (Lockscreen settings)
Line 707 TextAppearance.StatusBar.EventContent notification details (15 unread messages)
Line 712 TextAppearance.StatusBar.EventContent.Title notification (Bold: New Messages)
Line 847 Widget.TextView.ListSeparator details between lists (General, Music Controls)
Line 912 TextAppearance.SlidingTabNormal Unlock text on slider in lockscreen
Line 920 TextAppearance.SlidingTabActive unlock text pressed on slider in lockscreen
Too hard to get a screenprint of... its the same as the above except for when you actually hit the dot.
I still can't find this one
