Color strips in custom themes??? Some how I missed that one. Thanks for the info.
Nicely done bakers - It's
optional in Preferences->Colors (check the "Show strip colors" box)... AND comes with a Saturation slider. VERY cool!!!
To fix the yellow, or any other color not to your liking, click the "Other" button and adjust color to suit. The best I could do for yellow in default Tungsten theme was banana yellow with 100% saturation.
