Syntax

c = colorcube
c = colorcube(m)

Description

c = colorcube returns the colorcube colormap as a three-column array with the same number of rows as the colormap for the current figure (gcf). If no figure exists, then the number of rows is equal to the default length of 256. Each row in the array contains the red, green, and blue intensities for a specific color. The intensities are in the range [0,1], and the color scheme looks like this image.

After getting the colormap array, you can isolate a section of it to use as the color scheme.

Create a surface plot of a plane.

[X,Y] = meshgrid(-10:1:10);
Z = X + Y;
surf(X,Y,Z);

Figure contains an axes object. The axes object contains an object of type surface.

Get the colorcube colormap array, and isolate the red section (entries 39 to 44). Then use this section to color the whole surface.

c = colorcube;
c = c(39:44,:);
colormap(c);

Figure contains an axes object. The axes object contains an object of type surface.
