C_RSI

This is a normal RSI.

I like the default colors, but when you create a custom RSI the default colors (eg purple) are not the same as the built-in RSI colors.

This script is an approximation of the colors of the built-in RSI - the RSI itself, the background, the upper and lower boundaries.

Feel free to just grab the colors.

(imgur album shows identical in every respect, except you don't get the "source code" option for the built-in RSI.)

P.S. I use something like f.lux so the layout looks different on my screen, it may look weird on normal screens.
