On kate 15.08 I have dark color scheme where windows and view areas are dark with light colored text and buttons are bright with dark colored text. See the following images for a screen shot of the whole scheme: http://www.mediafire.com/view/yia44y25vzw35kt/scheme1.png http://www.mediafire.com/view/gz6tbw29gaakzir/scheme2.png I have gold buttons with purple fonts: http://www.mediafire.com/view/pwewds259vzrnft/scheme3.png (as you can see, my scheme has dark window, bright buttons with dark text on them). You've chosen to stylize kate by having the tabs take on the window colors rather then the button colors as is conventional. That's fair enough but in that circustance you shouldn't use the font color of the button text for the tab text because it may result in hard to read tabs: http://www.mediafire.com/view/gi06mdyc9swlg4n/scheme4.png (dark tab - same color as window, same text color as my button which also dark because my buttons are bright). If you use window background for the tabs, you should use window font text colors with it to be consistent. Reproducible: Always Steps to Reproduce: 1. Go to System Setting > Color Scheme and select Breeze Dark 2. Modify breeze dark so that the buttons are bright and button font is dark (not grey, dark). 3. Start or restart kate. You'll see that the tabs are hard to see.
