+Some code that will save virtual macbeth charts that show the difference between optimised matrices and non optimised matrices
+
+The function creates an image that is 1550 by 1050 pixels wide, and fills it with patches which are 200x200 pixels in size
+Each patch contains the ideal color, the color from the original matrix, and the color from the final matrix
+_________________
+|               |
+|  Ideal Color  |
+|_______________|
+|  Old  |  new  |
+| Color | Color |
+|_______|_______|
+
+Nice way of showing how the optimisation helps change the colors and the color matricies
