Frequently asked

Does Background Color work with React and Vue?
Background Color ships as React (Next.js included), Vue 3 (Nuxt included), plain HTML/CSS/JS - the same animation in each format. The React version uses the official useGSAP hook with cleanup handled; the Vue version is a real single-file component with <script setup>.
Do I need GSAP to use Background Color?
Yes. Background Color is built on GSAP directly, and GSAP has been 100% free for commercial use, including every plugin, since version 3.13. The component page lists exactly what to install.
Can I customize Background Color without editing code?
Background Color exposes 2 tunable controls in the Customize panel on this page - drag the values, watch the live preview respond, and the code you copy carries your exact settings.
Is Background Color free?
Background Color is part of the Annnimate Library, a paid subscription (from EUR 249/year). The live preview and customization run free on this page; the paste-ready code is for members.
Can I use Background Color in client projects?
Yes. The Annnimate license covers commercial and client work - ship Background Color on as many projects as you build, with no attribution required.
Does Background Color respect prefers-reduced-motion?
Yes. Every Annnimate component handles prefers-reduced-motion via gsap.matchMedia, so users who opt out of motion get an effectively instant, readable state.
