7 COLOUR VARIATION

using only basic colours will make your textures look really flat. In order to get some variation I decide to add galvanised textures on top of the layers, lowering the opacity to 20 per cent and changing their Blend mode to Overlay. This is also the time to use the previously created maps. I use the 8-bit Displacement and the Cavity map on top of the layers and change the Blending mode to Soft light and Overlay to get even more breakups.
