%% Sphere With Two Colors
% Create a sphere and color it using the pattern from a Hadamard matrix, which is a matrix that contains the values 1 and -1. Change the colors used in the plot by setting the colormap to an array of two RGB triplet values.

k = 5;
n = 2^k-1;
[x,y,z] = sphere(n);
c = hadamard(2^k);

figure
surf(x,y,z,c);
colormap([1  1  0; 0  1  1])
axis equal
