Multichromatic for Aptana Studio is a colorful theme that tries to facilitate the work on multiple languages, while being beautiful and usable on its own.
Each editor has its own palette:
- Yellow for JavaScript
- Green for CSS
- Blue for HTML and markup
- Violet for PHP
This facilitates the task when you're working on a multi-language code, but also can be helpful if you're constantly switching between editors, at least for avoiding visual boredom :D
