A theme is a style that’s applied to your entire app, activity or view hierarchy rather than an individual view. By default, Sendbird UIKit for React provides two themes: Light and Dark. Customized themes that fit your brand identity can also be created by changing the style and color set.

import { App } from "sendbird-uikit";
import "sendbird-uikit/dist/index.css";

const MyApp = () => {
    return (
        <Route id={'/chat'}>
            <App userId={userId} appId={appId} theme="dark" />

UIKit uses the Block, Element, Modifier methodology (BEM), which is a standard naming convention for classes in Cascading Style Sheets (CSS). Components can be customized by overwriting the applicable resources file in the UIKit's stylesheet.

You can use a colorSet prop of the App or SendBirdProvider component to determine the color set of UIKit. You need to put a string of objects to this prop. Refer to the list of color set here.

const myColorSet = {
    '--sendbird-light-primary-500': '#00487c',
    '--sendbird-light-primary-400': '#4bb3fd',
    '--sendbird-light-primary-300': '#3e6680',
    '--sendbird-light-primary-200': '#0496ff',
    '--sendbird-light-primary-100': '#027bce',
const MyApp = () => {
    return (
            <ChannelList />
            <Channel />
