Theme vs Custom Components

The theme only allows making cosmetic changes to the native components provided by Treble. For more control of components and editing their designs, its strongly recommended you use the Custom Components available in src/components instead.


The Treble app comes with a default theme (more themes coming in the future), that can be easily modified for any project's needs.

Theme is a list of CSS styles that are applied throughout the Treble components as a way to create a consistent styled and branded experience for the user. These styles include elements such as the color to use when highlighting/showing the selected state of an object, to the font size, color and typography.

Customizing the theme

To update any of the theme's values you just have to pass in the value you want to use into the theme object in the ThreekitProvider's props.

For example, if I want to change the primary color to a shade of green with the HEX value #25c2a0, I could do this in the following way:

import React from 'react';
import { ThreekitProvider } from '@threekit-tools/treble';
import App from './app';

const theme = {
primaryColor: '#25c2a0',

<ThreekitProvider theme={theme}>
<App />

const theme = {
primaryColor: '#1890ff',
