The vertical\n+            bars (left-to-right) are as follows; white, yellow, cyan, green,\n+            magenta, red, blue and black. Each bar should take up 1/8 of the\n+            sensor pixel array width.

The left half should have a\n+            smooth gradient, and the right half should have a quantized\n+            gradient. In particular, the right half's should consist of blocks\n+            of the same color for 1/16th active sensor pixel array width.
