Title: Pen Brightness and Brightness Effect Color Difference The main thing to point out here is that during the demonstration, you can see two clearly different colors using similar methods with the same initial color. The Scratch’s brightness effect is broken and I intend to prove why. In this demonstration, you can see different colors using an extremely accurate method and one using the Scratch brightness effect. There is also an additional one using a white overlay with a ghost (transparent) effect, and this one is more accurate!
