VistasUse custom color schema in MUI theme
I would like to configure some colors in my theme, which are used by some categories in my application.
So I've setup a theme and use this in my component.
theme.tsx
import { createTheme, Theme } from '@mui/material/styles'
import { red } from '@mui/material/colors'
export const theme: Theme = createTheme({
palette: {
primary: {
main: blue[800]
},
secondary: {
main: '#19857b'
},
cat1: {
main: red[700]
}
}
})
circle.tsx
import CircleIcon from '@mui/icons-material/FiberManualRecord'
import {theme} from '/shared/theme'
export function Circle() {
return (
<>
<CircleIcon style={{ color: theme.palette.cat1.main }} />
<CircleIcon style={{ color: theme.palette.cat1[200] }} />
</>
)
}
What I try to achieve is to set the color of some elements in a dynamic way. So the Circle in category 1 will get the color red. All colors which are needed are imported in the theme. I don't want to import all possible colors in the component itself.
But I also want to calculate the color of another element based on this. In the example above I would like to get 200 of red.

First off, don't use styles, it's harder to override and MUI has better alternatives (sx prop/styled function) which provide the theme object for you when passing as a callback, so change your code to:
<CircleIcon sx={{ color: theme => theme.palette.cat1.main }} />
Secondly, if you want to access other variants of the color like what you can with primary or secondary, use augmentColor() function to tell MUI generate the dark/light/contrastText colors automatically for you:
import {
createTheme,
ThemeProvider,
Theme,
lighten,
darken
} from "@mui/material/styles";
const { palette } = createTheme();
const { augmentColor } = palette;
createTheme({
palette: {
// this will tell MUI to calculate the main, dark, light and contrastText
// variants based on the red[500], and then merge the new properties with
// the color object itself. The end result will be something like:
// cat1: { '100': ..., '900': ..., light: ..., dark: ..., contrastText: ... }
cat1: augmentColor({ color: red }),
// this will tell MUI to calculate the main, dark, light and contrastText
// variants based on the red[100], no other shades are passed unlike the above.
cat2: augmentColor({ color: { main: red[100] } })
// light and dark variants are generated in augmentColor using lighten() and
// darken() function, if you want even more control, override the light and
// dark properties yourself like this:
cat3: augmentColor({
color: {
dark: darken(red[300], 0.6),
main: red[300],
light: lighten(red[300], 0.6)
}
})
}
})
