Turbo colormap array
c = turbo returns the turbo 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 is similar to that of the
jet colormap, but
the transitions between colors are more perceptually uniform than in
The color scheme looks like this image.
Reverse the Colormap
Plot a surface and assign the turbo colormap.
Get the turbo colormap array and reverse the order. Then apply the modified colormap to the surface.
c = turbo; c = flipud(c); colormap(c);
Get a downsampled version of the turbo colormap containing only ten colors. Then display the contours of the
peaks function by applying the colormap and interpolated shading.
c = turbo(10); surf(peaks); colormap(c); shading interp;
Compare Jet and Turbo Colormaps
Create a tiled chart layout containing two pseudocolor plots of the
peaks data set. The left plot uses the jet colormap, and the right plot uses the turbo colormap. Notice that the transitions between colors in the turbo plot are less severe than they are in the jet plot.
t = tiledlayout(1,2); [X,Y,Z] = peaks; % Left image ax1 = nexttile; s1 = pcolor(ax1,X,Y,Z); s1.EdgeColor = 'none'; s1.FaceColor = 'interp'; ax1.Colormap = jet; title(ax1,'Jet'); % Right image ax2 = nexttile; s2 = pcolor(ax2,X,Y,Z); s2.EdgeColor = 'none'; s2.FaceColor = 'interp'; ax2.Colormap = turbo; title(ax2,'Turbo');
