• Install MUI and create a new React app.
• Import the Avatar component from MUI.
• Use the Avatar component in your JS code.
• Add inline styles to adjust the random color.

Step 1: Install MUI and create a new React app.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import the Avatar component from MUI.

After installing MUI, you have to import your React component. To do this, add the following line to the top of your component file.

import * as React from "react";
import Avatar from "@mui/material/Avatar";
import Stack from "@mui/material/Stack";

Step 3: Use the Avatar component in your JS code.

You can use the Avatar component in your react js. For example, you can have the following code to display an avatar with an <Avatar {...stringAvatar("Guide Hub")} />.

<Stack direction="row" spacing={2}>
  <Avatar {...stringAvatar("Guide Hub")} />
  <Avatar {...stringAvatar("Viraj Mishra")} />
  <Avatar {...stringAvatar("Astha Mishra")} />
</Stack>

Step 4: Add inline styles to adjust the random color.

The stringAvatar function takes a name string and returns an object that has an sx property that contains bgcolor.

function stringAvatar(name) {
  return {
    sx: {
      bgcolor: stringToColor(name)
    },
    children: `${name.split(" ")[0][0]}${name.split(" ")[1][0]}`
  };
}

MUI material make mui avatar random color example.

The below code is an example of making random color of mui avatar using, stringAvatar function takes a name string and returns an object that contains an sx property with a bgcolor attribute set to the color generated by the stringToColor function and a children property with the first and last initials of the name.

import Avatar from "@mui/material/Avatar";
import Stack from "@mui/material/Stack";

function stringToColor(string) {
  let hash = 0;
  let i;

  /* eslint-disable no-bitwise */
  for (i = 0; i < string.length; i += 1) {
    hash = string.charCodeAt(i) + ((hash << 5) - hash);
  }

  let color = "#";

  for (i = 0; i < 3; i += 1) {
    const value = (hash >> (i * 8)) & 0xff;
    color += `00${value.toString(16)}`.slice(-2);
  }
  /* eslint-enable no-bitwise */

  return color;
}

function stringAvatar(name) {
  return {
    sx: {
      bgcolor: stringToColor(name)
    },
    children: `${name.split(" ")[0][0]}${name.split(" ")[1][0]}`
  };
}

export default function BackgroundLetterAvatars() {
  return (
    <Stack direction="row" spacing={2}>
      <Avatar {...stringAvatar("Guide Hub")} />
      <Avatar {...stringAvatar("Viraj Mishra")} />
      <Avatar {...stringAvatar("Astha Mishra")} />
    </Stack>
