Not exactly. It’s not that I can’t see the colors, I just need more contrast to pick up red or green. A grayish green looks the same as plain gray to me. A small bright green dot? Might as well be gray or brown. But a large, solid area of bright green or red? No problem at all.

Same here. I can figure it out, just not at a glance. Unfortunately, when it comes to video games, identifying small flashing colors at a glance is exactly the goal.
