Feature Request: highlight out of gamut colors with anything better than a plain color

When color managed mode is enabled, out-of-gamut colors get replaced by plain black by default, and you can edit the color in preferences. But the change is not really obvious, especially when the picked color is similar or the sizes are small.

I suggest a Display mode, for color managed mode that only shows out-of-gamut colors, so you can focus on fixing those without struggling to find them in the sea of objects.
