Hey here, that’s pretty easy to do, when you press the RMB you do a trace and if you hit a furniture blueprint you spawn a UMG widget that takes a furniture blueprint as a parameter and that lists the colors available. Each color will be buttons that when clicked will tell the furniture reference what color to change into. To have the furniture change colors you need to create a material that takes a parameter for the color, then on begin play you create a dynamic material and set it on the furtniture mesh, when you pick a color you set the color parameter to the color selected.
