Hello Marcus, Thanks for your hint. By editing the .qss file I was able to improve all my plots.
I’m not sure all will agree these are the best colors, but I like them. I started with the projector.qss and then reduced the font size and increased the plot color brightness. These updates are in the attached nsf.qss file that’s now in our designs. An unexpected big improvement was the ability to change the font size.
