Why are you using a hardcoded color?

same reason, no need to expose a new property because it's different just in dark bootstrap theme.

CHECKBOX:

1. For Empty Invalid checkbox when on Hover the tick should be Error 500
2. Something I've noticed- there is a color style called “ disabled-indeterminate-color” that uses secondary 100, and it is not used with the actual disabled indeterminate state here which is good because the right color is grays.400.

RADIO BUTTON:
All good

SWITCH:
All good
