Summary 💡

Currently, components like OutlinedInput use hard-coded border-color values. This makes it very inconvenient to set a border color for all inputs in a custom theme:

 theme.palette.mode === 'light' ? 'rgba(0, 0, 0, 0.23)' : 'rgba(255, 255, 255, 0.23)';

Adding a borderColor property in theme would make it much more easier to handle all border colors of all MUI components at once when using a custom theme.

Motivation 🔦

I am using a custom theme with a custom color for the "palette.divider", which I use a lot as borderColor: divider.

I ran into a lot of trouble when I tried to match colors of my inputs to my dividers and borders of other elements. Setting sx={{borderColor: divider}} on every textField input is inconvenient.

I imagine the same would apply to all other components that might have borders?
