I hope color recognition will be a lot better now that the Cataracts have been removed.
Up until a few years ago, I flew primarily Helicopters and color itself didn't mean much to me, I think more so because the target was too small.
I have tried all kinds of combos (on heli's) including every fluorescent made. The only thing that works is contrast. If I made the windshield an opposing color it was much easier to recognize attitude, still a small target but greatly improved.

On fixed wing, I have also found the Cub yellow to be better for me than light yellow. I was using it with dark blue, it will be interesting to see if red will be better now. Before the surgery, red looked pretty much black at altitude.

Large stripes or blocks as you show are without a doubt better for me also. I have a 30% Extra with Cub yellow and what I thought at the time, BIG checker board blue squares, Ha, it just looks like a blur at altitude.
