Most analyses of visual signals concentrate on the properties of the individual colours, yet signals consist of several colours and are more than random sets of colour patches.  It is likely that the geometry of the individual colour pattern components is important in signalling.  Possible effects include special effects resulting from particular colours seen together in groups, blended together by visual acuity limits, arranged in particular patterns by size and/or shape, presented in particular sequences, or moved in particular directions relative to pattern geometry.  I will also discuss display colour use as mechanisms of chromatic adaptation which enhance other aspects of colour patterns.  Pattern geometry may be as rich or richer than what we have discovered about colours.
