Spring colormap array
c = spring returns the spring colormap as a three-column array with the
same number of rows as the colormap for the current figure. 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.
Reverse the Colormap
Plot a surface and assign the spring colormap.
Get the spring colormap array and reverse the order. Then apply the modified colormap to the surface.
c = spring; c = flipud(c); colormap(c);
Downsample the Spring Colormap
Get a downsampled version of the spring colormap containing only ten colors. Then display the contours of the peaks function by applying the colormap and interpolated shading.
c = spring(10); surf(peaks); colormap(c); shading interp;

R2019b: Colormaps have 256 colors by default
Starting in R2019b, colormaps have 256 colors by default.
In R2019a and previous releases, the default size is 64. If you have code that
depends on a colormap having 64 colors, specify the number of colors when you set
the colormap for the figure, axes, or chart. For example,
colormap(spring(64)) sets the figure's colormap to the
Alternatively, you can change the default colormap for all figures within your MATLAB® session:
