A Model of Islamic Rectilinear Interlaced Lattices

COLOUR

The colours used in the actual RIGE usually emphasize both the continuity of the frames, the contrast with the inner figures, and the symmetries. Contiguous colours are thus different and contrastive as a general rule. From a minimum of two colours, for frames and figures - figures and background-, we can pass to a great number; but the artistic use of this richness is difficult, and a banal colouring can be the result, especially in computer graphics.

An important quality of the colour is the Texture, which improves the variation without breaking the basic colours. This texture, present in every natural material, must be simulated in computer work; PUERTRA has implemented some possibilities in this direction, as the figures show.
