Virtual colors

Virtual color is a special color which values should be different for light and dark color schemes.
To define a virtual color, use virtualColor function which accepts an object with the following
properties as a single argument:

name – color name, must be the same as the key in theme.colors object
light – a key of theme.colors object for light color scheme
dark – a key of theme.colors object for dark color scheme

To see the demo in action, switch between light and dark color schemes (Ctrl + J):

import { createTheme, MantineProvider, virtualColor } from '@mantine/core';

const theme = createTheme({
  colors: {
    primary: virtualColor({
      name: 'primary',
      dark: 'pink',
      light: 'cyan',
    }),
  },
});

function App() {
  return <MantineProvider theme={theme}>{/* Your app here */}</MantineProvider>;
}

import { colorsTuple, createTheme } from '@mantine/core';

const theme = createTheme({
  colors: {

  useMutationObserver(
    (mutations) => {
      mutations.forEach((mutation) => {
        if (mutation.type === 'attributes' && mutation.attributeName === 'dir') {
          mutation.target instanceof HTMLElement &&
            setLastMutation(mutation.target.getAttribute('dir') || '');
        }
      });
    },
    {
      attributes: true,

      </Text>

      <Text mt={10}>Direction was changed to: {lastMutation || 'Not changed yet'}</Text>
    </>

    <>
      <Text>Current value: {value}</Text>
      <Group my="md">
