I am creating a flat plane, I want the color of the plane to be a gradient. I tried using the colormap copper but it keeps it black because it is flat. How can I adjust the color?
[x,y] = meshgrid(1:1250,1:760);
z = zeros(size(x));

Jossie - what do you expect the output to look like? Can you us how you expect the gradient to be applied to your 2D data?

Not necesarly this color scheme, but I want my flat plane to look something like this. Go from a dark color to a lighter one (without the grid). As I mention my plane is flat which does now allow me to variate the color.

Use something like this:
surf(x,y,z-1,x+0.5*y),shading flat
You can use whichever linear combination of x and y to have your gradient in your desired direction.
