PowerToys is great, in particular PowerToys Run.

I'd use PowerToys Color Picker more, but it lacks contrast ratios/accessibility information, which is where it would be most useful to me. It was suggested on their GitHub but didn't gain much traction:

9 times out of 10, I am getting color information to run these exact checks, so it would just save an extra step.
