I am not sure about fastest way, one way:
[~,~,I]=histcounts(peaks,5);
I = I-1;
imagesc(I)
colormap([1 0 0; % color of 0 value
0 1 0; % color of 1 value
0 0 1; % color of 2 value
0 0 0; % color of 3 value
1 1 1])% color of 4 value
set(gca,'Clim',[-0.5 max(I(:))+0.5]);
colorbar
saveas(gcf,'test_image.png');
