How to disable Material-UI contrast ratio console errors?

My console is full of

Material-UI: the contrast ratio of 2.590660811372324:1 for #fff on #5EB44B falls below the WCAG recommended absolute minimum contrast ratio of 3:1.

error messages which I would like to hide. Is there a way how to do that? I've done the research but could find anything useful.

Here is my createMuiTheme code

createMuiTheme({
  themeName: 'radovix',
  palette: {
    primary: {
      main: '#5EB44B'
    }
  },
  contrastThreshold: 2
});

Note, I'm aware that best approach would be changing the colors that I'm using and therefore solving the error, but that is not possible in my case.

This console error is produced by getContrastText which is used whenever a contrastText color is not explicitly specified.

Instead of specifying contrastThreshold: 2, I would recommend explicitly specifying the desired contrastText color for those cases where the default contrastThreshold of 3 does not pick the one you want. Customization of contrastThreshold is really only intended for increasing the threshold -- not for decreasing it.

Here's a working example:

import React from "react";
import { createMuiTheme, ThemeProvider } from "@material-ui/core/styles";
import Button from "@material-ui/core/Button";
import { common } from "@material-ui/core/colors";
const theme = createMuiTheme({
  palette: {
    primary: {
      main: "#5EB44B",
      contrastText: common.white
    }
  }
});

export default function App() {
  return (
    <ThemeProvider theme={theme}>
      <Button color="primary" variant="contained">
        Primary Color Button
      </Button>
    </ThemeProvider>
  );
}
