Limited Colours In Free Version Of Sketchup

Hello. I cannot seem to find how to create unique colours. I can navigate to the colour selection TAB but unable to bring up the colour pallet or find a way to create a new colour.

You will need SketchUp Go to be able to modify the materials.

You can create them in a 2D graphic editing software and import those textures (JPGs).

Or you can search 3D Warehouse.

Thankyou. I do not wish to create materials, I just want to use different colours than what are available. But maybe this is not possible either?

That would still be different materials. Colors are materials.
