Error While Defining Brush in PSE 2020
I am trying to define a brush that will be a watermark on dark background photos. It is white 18 pt text on a transparent background. I get the following error:

If I change the R,G,B color values to 254,254,254 instead of the default 255,255,255, the Define Brush command works perfectly.
Am I doing something wrong? Why won't it work with pure white color?
