Just something quick before I go to bed. That aa is hurting my eyes. AA is to make things appreat smooth and not make them blurry.

The AA color, dark red, is too saturated. You probably thought that because the yellow and the purple are both 100% saturated (in HSV) that the intermediate would be 100% too. But no - intermediate shades between to changing hues become less saturated. Explaining why is difficult, maybe somebody else can.
The AA color can also be a bit brighter because of how bright yellow is compared to the rest of the hues.

I also removed some AA on 45 degree lines.

I'm not sure, but I'm pretty sure it's because Gray is the halfway point between complements.  In your first post, your colors are moving around the color wheel:

A more extreme example would be to travel through the center first:

But your colors aren't perfect complements, so that wouldn't be optimal.  The gradient would travel through the color wheel:

Which means your colors should be somewhere around here.  I also edited the AA:
