Kelly, pcolor does color interpretation for the faces according to the colors of the vertices (which are not drawn), so the color of any one face is not directly associated with a single point value and instead is an interpolation according to what is nearby.

That's true only if the shading scheme is set to interpolated. Otherwise, the color is associated with a single vertex, and in Image Analyst's example, each cell with a 1 in its upper right corner is indeed the same color as other 1-cells, regardless of its neighbors.

I am using pcolor(X,Y, Z)
In that case, how I do this?
