The perceiver's position in an architectural, or merely physical space, determines the dimensional imperatives of that person's mental qualia. It is interesting to note that each viewer of a rainbow stands at the centre of their very own optical illusion; that light, once split into its component colours, streams - within the constraints of nature - upon a mathematically defined axis, of no more or less than 42° relative to each perceiver's location. There is no definitive rainbow, indeed no absolute dimension from which one could view a rainbow, a horizon or simply a piece of architectural design.
