Ability to change color of font or any card in the UX

We were asked by our client if we could use different font (type) or color on the grids published on the UX. Additionally, it would be of great help if we could also be able to apply a color to any published card on the UX (currently, we can only toggle between a transparent background or it defaults to white )
