Palette
The palette enables you to modify the color of the components to suit your brand.
Intentions
A color intention is a mapping of a palette to a given intention within your application. The theme exposes the following color intentions:
- primary - used to represent primary interface elements for a user.
- secondary - used to represent secondary interface elements for a user.
- error - used to represent interface elements that the user should be made aware of.
- warning - used to represent potentially dangerous actions or important messages.
- info - used to present information to the user that is neutral and not necessarily important.
- success - used to indicate the successful completion of an action that user triggered.
The default palette uses the shades prefixed with A
(A200
, etc.) for the secondary intention,
and the un-prefixed shades for the other intentions.

Customization
You may override the default palette values by including a palette object as part of your theme.
If any of the palette.primary
,
palette.secondary
,
palette.error
,
palette.warning
,
palette.info
or
palette.successs
'intention' objects are provided, they will replace the defaults.
The intention value can either be a color object, or an object with one or more of the keys specified by the following TypeScript interface:
interface PaletteIntention {
light?: string;
main: string;
dark?: string;
contrastText?: string;
}
Using a color object
The simplest way to customize an intention is to import one or more of the provided colors and apply them to a palette intention:
import { createMuiTheme } from '@material-ui/core/styles';
import blue from '@material-ui/core/colors/blue';
const theme = createMuiTheme({
palette: {
primary: blue,
},
});
Providing the colors directly
If you wish to provide more customized colors, you can either create your own color object, or directly supply colors to some or all of the intention's keys:
import { createMuiTheme } from '@material-ui/core/styles';
const theme = createMuiTheme({
palette: {
primary: {
// light: will be calculated from palette.primary.main,
main: '#ff4400',
// dark: will be calculated from palette.primary.main,
// contrastText: will be calculated to contrast with palette.primary.main
},
secondary: {
light: '#0066ff',
main: '#0044ff',
// dark: will be calculated from palette.secondary.main,
contrastText: '#ffcc00',
},
// Used by `getContrastText()` to maximize the contrast between
// the background and the text.
contrastThreshold: 3,
// Used by the functions below to shift a color's luminance by approximately
// two indexes within its tonal palette.
// E.g., shift from Red 500 to Red 300 or Red 700.
tonalOffset: 0.2,
},
});
As in the example above, if the intention object contains custom colors using any of the "main", "light", "dark" or "contrastText" keys, these map as follows:
- If the "dark" and / or "light" keys are omitted, their value(s) will be calculated from "main", according to the "tonalOffset" value.
- If "contrastText" is omitted, its value will be calculated to contrast with "main", according to the "contrastThreshold" value.
Both the "tonalOffset" and "contrastThreshold" values may be customized as needed. The "tonalOffset" value can either be a number between 0 and 1, which will apply to both light and dark variants, or an object with light and dark variants specified by the following TypeScript type:
type PaletteTonalOffset = number | {
light: number;
dark: number;
};
A higher value for "tonalOffset" will make calculated values for "light" lighter, and "dark" darker. A higher value for "contrastThreshold" increases the point at which a background color is considered light, and given a dark "contrastText".
Note that "contrastThreshold" follows a non-linear curve.
Example
<ThemeProvider theme={theme}>
<Button color="primary">Primary</Button>
<Button color="secondary">Secondary</Button>
</ThemeProvider>

Dark mode
Material-UI comes with two palette types, light (the default) and dark.
You can make the theme dark by setting type: 'dark'
.
While it's only a single property value change, internally it modifies several palette values.
const darkTheme = createMuiTheme({
palette: {
type: 'dark',
},
});
The colors modified by the palette type are the following:
Typography
palette.text.primary
#fff
palette.text.secondary
rgba(255, 255, 255, 0.7)
palette.text.disabled
rgba(255, 255, 255, 0.5)
Buttons
palette.action.active
#fff
palette.action.hover
rgba(255, 255, 255, 0.08)
palette.action.selected
rgba(255, 255, 255, 0.16)
palette.action.disabled
rgba(255, 255, 255, 0.3)
palette.action.disabledBackground
rgba(255, 255, 255, 0.12)
Background
palette.background.default
#303030
palette.background.paper
#424242
Divider
palette.divider

User preference
Users might have specified a preference for a light or dark theme. The method by which the user expresses their preference can vary. It might be a system-wide setting exposed by the Operating System, or a setting controlled by the User Agent.
You can leverage this preference dynamically with the useMediaQuery hook and the prefers-color-scheme media query.
For instance, you can enable the dark mode automatically:
import React from 'react';
import useMediaQuery from '@material-ui/core/useMediaQuery';
import { createMuiTheme, ThemeProvider } from '@material-ui/core/styles';
import CssBaseline from '@material-ui/core/CssBaseline';
function App() {
const prefersDarkMode = useMediaQuery('(prefers-color-scheme: dark)');
const theme = React.useMemo(
() =>
createMuiTheme({
palette: {
type: prefersDarkMode ? 'dark' : 'light',
},
}),
[prefersDarkMode],
);
return (
<ThemeProvider theme={theme}>
<CssBaseline/>
<Routes />
</ThemeProvider>
);
}
Default values
You can explore the default values of the palette using the theme explorer or by opening the dev tools console on this page (window.theme.palette
).
