The "Colours" group allows users to create a colours and textures library that will be used to generate a building with a specific aesthetic, giving it a more realistic appearance.

The texture library contains a variety of textures classified by groups (concrete, stone, timber, ceramic, grass, marble, stoneware, brick, steel, carpet and glass).

The scale factor of the textures can be changed and the desired level of opacity can be applied.

Furthermore, from the "Own elements" section, textures can be shown or hidden during modelling.
