Subtle variant and color prop of Button, ActionIcon

[topaz briar]

I noticed that Button and ActionIcon color prop were not working correctly when using a theme color with a shade greater than 6. I then found the defaultVariantColorResolver using a Math.min to ensure 6 is the max

I can override with a custom variantColorResolver in the theme, but was curious why the subtle variant has that implementation detail for color.

@steady beacon In case you can share some insights into this.

It is intended behavior to maintain proper contrast in dark theme.
