Instead of navigating through /Applications
, the easiest way of accessing built-in packages in Sublime Text 3 is to use @skuroda's excellent PackageResourceViewer
plugin, available through Package Control. Once installed, restart Sublime and hit ⌘ShiftP to open the Command Palette. Type prv
to bring up the PackageResourceViewer
options, and select Open Resource
. Scroll down to Color Scheme - Default
, hit Enter, then scroll down to select Cobalt.tmTheme
and hit Enter. You can now hit Esc to get rid of the menu, and start looking through the theme file for the bits you want to copy.
Good luck!
