NColors = 10;
RGBn = linspecer(NColors);
moon = imread('moon.tif');
imshow(moon);
quiver(0,0,5,5,'color',mycol); %mycol is conditionally selected from RGBn; multiple arrows are plotted on the image
colorbar % shows the colorbar of moon. But I want to display the colorbar of my custom 10 colors. Is that possible?

colormap(RGBn)
after the imshow() and before the colorbar()
