I just finished a simple light skin modification for FL Studio 9. I was mainly doing it for myself but decided to share it in case someone else likes it too. The theme is white and green and is strongly based on the default skin. Feel free to comment, modify and redistribute it.
The main idea was just to make a bit happier-looking interface to work with, since I was a bit bored with the default skin color.
The installation instructions are included in the .zip file in case someone doesn't know how to apply a skin.
Please leave your comments to this thread. I haven't uploaded the skin anywhere else since I mostly did it for myself.
