Is it possible to paint customized cabinets with colors using HEX CODES?

Pt 1:You can use hex/RGB colors on anything. You need access to an art type program: Affinity photo, Clip Studio Paint, Corel or something like that. Once you have the hex/rgb code you need to create a jpg file with only that color covering the whole page. Save the jpeg to laptop, upload the file as a 2D texture as a custom map, use the jpeg dimensions in the upload box. When done you will be able to apply to anything. For any other model-use replace material function to apply.

These same methods can be used for custom models. You just have to be creative with your work arounds thru what HS allows. Good Luck.

Pt3: You can apply hex/RGB code colors to walls etc. Click on the wall, tile flooring option. On the right side menu you will see a box "RGB" click on that, hit the arrow and input the hex/rgb code.

Pt 2: Apply the color to any model in the room with the custom furniture. Then when in custom furniture interface-select cabinet by part and use the custom material brush to apply the color to the custom furniture.You may have to use this method because sometimes custom furniture may not allow you to get to your material upload folders.
