However, it support the use of `(N, M, 3)` or `(N, M, 4`) dimensional arrays to encode rgp or rgba data directly. This allows to write routines that encode e.g. 2D dimensional information like (orientation in color, strength in darkness) or 3D date (directly mapped to rgb).\r\n\r\nThere seems no way to combine both non-equidistant aces and rgb(a) support in matplotlib.  \n\n### Proposed solution\n\nWould it be possible to add the rgb and rgba options to `pcolormesh`/`pcolor` as well? \r\n\r\nOr are there other options for tackling this issue? \r\n\r\nIs there actual interest in such an option and would it be worth to add code fo it?
