Plotting points in the complex plane with certain color

Hey everyone

I have a uint8 matrix in the format of

A( 1:512 , 1:512 , 1:3)

storing information about a RGB map. I also have a second matrix B

B( 1:512 , 1:512 )

holding complex numbers.

Now I would like to plot for the entry (x,y) of B a point on the complex plane with the coordinates B(x,y) and the color of A(x,y,1:3). Do you have any idea how to do that?
