One dimensional colour

From one dimension, a flat colour without depth, without width, is made

where to look for this illusion
an illusion that appears as space and depth

I rather like this idea from: http://en.wikipedia.org/wiki/Riemann_surface

In mathematics, particularly in complex analysis, a Riemann surface, first studied by and named after Bernhard Riemann, is a one-dimensional complex manifold. Riemann surfaces can be thought of as "deformed versions" of the complex plane: locally near every point they look like patches of the complex plane, but the global topology can be quite different. For example, they can look like a sphere or a torus or a couple of sheets glued together.
