This question already has an answer here:

Here is a simple example of a rotational symmetric plot

ParametricPlot [{x, y }, {x, -1, 1}, {y, -1, 1}, 
RegionFunction -> Function[{x, y}, x^2 + y^2 < 1], Mesh -> 5, 
MeshFunctions -> (Sqrt[#1^2 + #2^2 ] &), 
ColorFunction -> (Hue[  Sqrt[#1^2 + #2^2 ]  ] &), AxesLabel -> {x, y }]

enter image description here

I took the same function as meshfunction and colorfunction expecting rotational symmetrical mesh and coloring.

Any idea why the coloring isn't symmetric?
