Can you customize the colors, add pictures (replacing the placeholders) and other things in the Relume platform or do you have to export it to Figma before you'd be able to do that?
today - you'll need to export to Figma/Webflow to do those things.
In the future:
yeah, that was a way to provide a quick start to bringing colors into webflow before Webflow Variables - color palettes are not as helpful now with variables and there's currently no way to "inject" variables through copy/paste.
