At first, thank you for simply the best text editor! This is really an ideal code and text editor.
I use Sublime Text for web development very intensively, and the only thing that I missed there is the color editing functionality.
Now I would like to present a color editor application which can be helpful for Sublime Text users: (http://www.color-tools.com/)
How does it work?
Just select a color in Sublime Text and press Ctrl+C+C to edit it.
The color can be in any HTML valid format: #ff0000, rgba(255, 0, 0, 1), red, etc.
The app has also built-in image editor and converter, and a screen capture utility which can capture alpha channel (Aero, shadows, etc.).
For the present, the app is Windows only.
Licensing policy is similar to Sublime Text licensing policy: the trial version is fully-functional with no enforced time limit.
Due to this is an app which only acts as a plugin, it can work not only with Sublime Text, but everywhere. Use Ctrl+C+C as a universal shortcut to open the app.
Hope you will find it useful. The feedback is welcome.
