I am color blind, and it's hard for me to tell colors apart. I am looking for a tool or app or way to help me know the name of the colors I am working with on powerpoint on my Mac: is it green, blue, red, pink....



So far, I had to rely on 2 ineffective workarounds:
- RGB color codes obtained with color pickers, but I need to guess the actual color name from RGB codes, not easy, and it's not always on.
- Color names given by the built in interface where it's available. but color names are slow to appear and it's far from being comprehensive.

Are there any other way?

For information, I am using Powerpoint 2011 for Mac.
