[material-ui][Switch] Unsupported color after upgrade @mui/material to 5.15.13 about material-ui HOT 4 OPEN

Hello,
I followed the steps listed to reproduce the issue with the Switch component using MUI v.5.15.13 and v.5.15.15.

Environment:
Chrome browser
MUI version tested: 5.15.13 and 5.15.15

Steps Reproduced:

Updated to MUI v.5.15.13 and v.5.15.15.
Implemented ThemeProvider using the specified RGB format for the primary color in the palette.
Added the Switch component with color="primary" and checked={true}.

Outcome:

Received the error as reported: "MUI: Unsupported 58, 53, 65 color. The following formats are supported: #nnn, #nnnnnn, rgb(), rgba(), hsl(), hsla(), color()."
This confirms that the issue persists as its described. It seems that MUI does not currently support plain RGB values without the rgb() function. It might be helpful to specify in the documentation that colors need to be provided in the rgb() or other supported formats.

The error is self-descriptive, what you are providing is not a valid color. Which version did this work with? I tried an older version (before v.15.13), and it still yields the same error: https://stackblitz.com/edit/react-ceuj3r-hci311?file=package.json
