This need came up before I had script for it but it was lost in the other dead forum.
So I am doing this again and sharing it here:
Required by this post: Is there a way I can average and blend colors of... (on reddit)
This plug-in simply gets average RGB values using histogram of active layer (and of selection area if once exists) and sets the average RGB as Context ForeGround Color so you can work with that color however you want.
Menu Location: Python-Fu/Get Average Color.
You can set a short cut key to it if you use it often.
Here's the code (attached zipped .py as well):
Code: Select all
