Copper colormap array

  • Copper colormap



c = copper returns the copper 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.

Sample of the copper colormap


c = copper(m) returns the colormap with m colors.

c = copper;
c = flipud(c);

Get a downsampled version of the copper colormap containing only ten colors. Then display the contours of the peaks function by applying the colormap and interpolated shading.

c = copper(10);
shading interp;
