Customization MUI theme.palette insufficient : 10 hues of Primary not accepted?

As of my knowledge cutoff date in September 2021, the Material-UI (MUI) library provides a default color palette with various shades and tints for the primary, secondary, and other colors. By default, MUI defines a palette with 10 hues for each color, ranging from 50 to 900, where 50 is the lightest shade and 900 is the darkest shade.

However, there might be situations where you need to customize the color palette further, including using more than 10 hues for a particular color. While MUI does not provide a direct API to customize the number of hues, you can still achieve this customization by creating a custom theme with your desired color palette.

Here's an example of how you can create a custom MUI theme with more than 10 hues for the primary color:

jsxCopy code
import { createTheme } from '@mui/material/styles';

const customTheme = createTheme({
  palette: {
    primary: {
      50: '#f5f5ff',
      100: '#ebf0ff',
      200: '#c2d3ff',
      300: '#99b7ff',
      400: '#4d80ff',
      500: '#0059ff', // Your primary color
      600: '#0051e6',
      700: '#0047cc',
      800: '#003db3',
      900: '#002b80',
      // Additional hues
      1000: '#00226b',
      1100: '#001957',
      1200: '#001040',
      // Add more as needed
    },
  },
});

// Now you can use customTheme throughout your app instead of the default MUI theme

In this example, we've defined 13 hues for the primary color, from 50 to 1200. You can adjust the hues and their corresponding colors according to your requirements.

Keep in mind that while this approach allows you to define custom hues for a specific color, it might not be a perfect solution if you need to change the hues for all colors in the palette. In such cases, you may need to override the default MUI color palette at a lower level or consider other theming solutions.

As of the knowledge cutoff date, MUI is continually evolving, and there might be new features or updates related to theming and color customization. Always refer to the official MUI documentation or the latest release notes for the most up-to-date information and best practices.
