% Show a CIELAB color cube composed of 25^3 balls
% note: Matlab CIELAB colorspace goes approx. from -108 to +100 as measured
% with: colors = rgb2lab(jet(100)); min(colors(:)), max(colors(:))
figure();
[X,Y,Z] = meshgrid(linspace(-108,100,15));
colors = lab2rgb([double(X(:)),double(Y(:)),double(Z(:))]);
scatter3(X(:),Y(:),Z(:),100,colors,'filled');
xlabel('L'); ylabel('a'); zlabel('b');
