I like the Sublime Text 2 default color scheme Monokai alot. The only problem is the tab colors, the selected tabs and the rest of the tabs all look the same (almost). How can I change only the selected tab color for this theme.
You need to dig pretty deep into theme customization to do that:
Since your theme is Monokai (medium-dark) go to "Packages/Theme - Default/Default.sublime-theme"
From lines 528 to 531 are your answers...
Either you hack by changing tint_modifier or layer2.opacity
OR
You go right at "medium_dark_unselected_tab_bg2.png" and try changing it by "light_unselected_tab_bg2.png" for example.
Either way I recommend you using Soda Theme! A really great and easily configurable theme too!
