Details:

In the following code the legend of the figure is not updated to include the
new colormap (in MATLAB it is):

% orange shades
orange=[237/255,112/255,20/255];
tangerine=[249/255,130/255,40/255];
merigold=[253/255,174/255,29/255];
cider=[181/255,103/255,39/255];
data=ones(4,1);
figure
pie(data);
colormap(gca,[orange;tangerine;merigold;cider]);
labels={'orange';'tangerine';'merigold';'cider'};
legend(labels,'Location','eastoutside');
title('orange shade wheel');

If the line:
colormap(gca,[orange;tangerine;merigold;cider]);
Is modified to:
colormap([orange;tangerine;merigold;cider]);
Then the colormap will be updated to update the legend.
However if subplots are used, it applies the last specified colormap to every
subplot in the plot.
