Highlime

Make Sublime Text 3 even more high.

Plugin which changes your current color scheme gradually in real time (if time is real of course)

What you need to know before the trip

Sublime Text build 3149 or later required - only "new" .sublime-color-scheme format supported (all default color schemes and some of user-written)
It's impossible for now to change color scheme of Sublime Text in-memory.
So main thing this plugin does is repeatedly rewriting the file with current color scheme modification (every 0.2 sec by default) so you'll better to have an OS installed on a SSD to run Highlime (or you can set greater time_iteration_step for HDD)
Because of the problem described previously we can't yet make a real disco with this plugin - we're limited by IO operations speed

* On Mac use Cmd ⌘ instead of Ctrl

Turn on some good music
While using color scheme which you like the most choose View -> Highlime -> Get high or press Shift+Ctrl+L+S+D
To pause plugin (if you are okay with current colors) choose View -> Highlime -> Take a nap or press Shift+Ctrl+Y+W+N
To revert changes completely choose View -> Highlime -> Guys I'm sober or press Shift+Ctrl+C+O+P or just change current color scheme to another one

"Take a nap" command does not work if it was called from Command Palette (works only from hot keys / main menu)
Caused by this bug: sublimehq/sublime_text#3404
Hope it will be fixed in Sublime Text 4
With very small values of time_iteration_step (depends on your system drive speed and current load) Sublime Text can throw errors on color scheme load.
This problem cannot be resolved automatically for now (we have no method to know if settings were loaded fully before rewriting color scheme file).
To resolve this issue manually you'll need to try a greater value of time_iteration_step in preferences
