I was doing some experimenting and I've discovered a more accurate and detail orientated color for quick masking. Might be a very simple change but I think it would be a significant improvement.
Using a layer in Subtract mode and the color #0cff00.
The traditional red has always been a blessing but I was amazed at the difference this is making. It defines the edges of the mask more accurately and really exposes every single tiny little detail being masked. It also reveals the incredibly hard to miss subtle tonal differences in shading especially when dealing with white on white.
I think this would provide users with an improved quick masking ability, but it may also be utilized as a way for AI to better discern masking edges, background removal and other similar processes.
Thanks!
