Interpreting Indexed and Truecolor Data

MATLAB interprets the patch color data in one of two ways:

Indexed color data -- Numerical values that are mapped to colors defined in the figure colormap
Truecolor data -- RGB triples that define colors explicitly and do not make use of the figure colormap

The dimensions of the color data (CData or FaceVertexCData) determine how MATLAB interprets it. If you specify only one numeric value per patch, per face, or per vertex, then MATLAB interprets the data as indexed. If there are three numeric values per patch, face, or vertex, then MATLAB interprets the data as RGB values.
