I use version Eclipse 2021-03 (4.19.0) and I have trouble seeing the changes in the Eclipse Compare View. I tried changing the colors in the Preferences > General > Appearance > Colors and Fonts and there in Text Compare:
The deletion color in the setting is (255, 0, 0), thus a powerful red. The resulting colors in the compare viewer however don't look like the setting:
The result contains a red that is barely visible (255, 204, 204). The color saturation is lower and brightness much higher.
I guess the colors are somehow merged with other color settings. So how I can set or compute the colors that I would like to see?
