Add this file to your project and begin using the attributes.

DarkContainer

Draws a dark box with optional borders.

ColorBox

Draws a colored box with an automatic color using the type's hashcode.

This file doesn't seem to do what it's supposed to. The DarkBoxAttribute() method doesn't even exist in it and there is not mention of color anywhere in the file.

Sorry, I think I mixed it up with another script. I will update this soon, sorry for the confusion.

No worries, thanks for putting it up to begin with. I just had to say something since I was really looking forward to implementing the Colorbox into some editors. :D

I think it still isn't updated with the correct script.

Any progress?

I finally got around to doing this, thanks to your reminder. The file was on my old annoying laptop, so I've been procrastinating and kept forgetting about it. Enjoy!
