A rosette
The type of symmetry is different according to whether we decide to ignore the colouring or not; in the first case, the symmetry is cyclic of type C12, in the second one it is still a cyclic symmetry, but the type is C6. If you look at the central part of the drawing, you will notice the absence of symmetry axes in both cases and the breaking of symmetry due to the colouring.
