Perceptually Uniform Color Spaces

I'm not sure. It's hard to say because RGB is a bad representation of the color semantics anyway. Try visualizing the images in HSV/HSL/LAB space instead.

For this there are things like the Lab color space!https://en.wikipedia.org/wiki/CIELAB_color_space

Then go all the way and use perceptually uniform colorspace. But that has complicated relationship to RGB used everywhere.

Even better, convert to HSL or CieLAB. RGB is not at all how our eyes see things.

What color space does this use? Is it HSV? You should consider moving to something more perceptually based; all these look slightly off to me.

Surely this should be using a perceptually uniform color space like OKLab rather than HSL!

I've been peripherally interested in colo[u]r science for a while, and as a software guy was amazed to discover the complexities of accurately describing and computing color across a not-so-wide range of devices (my LCD screen, your LCD screen, that projector, this printer...).For example, I was looking for a way to find "perceptual distance" between colours, since the standard RGB rainbow gives more space for green than, say, yellow. Turns out there are colour spaces for that:

Is there a primer to colour spaces for a beginner?

Why not use CIE L*ab, since that colorimetric system is based on human perception or difference?

If you want to do something meaningful with colors, don't use RGB, and don't use HSL (which is based on RGB). These spaces are problematic. For instance, pure blue and pure green in RGB space have very different lightness. Here's a picture of the region of colors covered by RGB:https://en.wikipedia.org/wiki/HSL_and_HSV#/media&#
