Display brightness of intervals in the matrix

an option to see brightness for intervals within their scale degree would be nice. color would probably be a good way to do it. you could go blue->red, or maybe blue->yellow(so you can still see cs violations), dividing the colors between into whatever the variety that degree has. here are some concepts i did in google sheets. i did diasem(mv3, and always 3) and blackdye(mv4, sometimes 2, 3 or 4) as examples for light and dark mode. honestly this helps me a lot to analyze stuff. and maybe for colorblindness accessibility you could just have an option for a grayscale version.

0.5deg recommended these color schemes, which ascend in brightness (or perceptual brightness) while using many colors and roughly consistent saturation

I could probably tackle this.
