Gray Patches
• Grays proceed from white (E1) down to black (E6) in 20% steps.
• Patches D2 to D6 are extra gray patches that provide 10% steps.
• A zigzag path from A1 to A6 will cover the 10% gray ramp in order.
• An additional 95% patch is located at D1, and an additional 5% patch
is located at C6 for more detail near white and black.
• The same 10% ramp patches are repeated on the back of the chart,
with a large 50% gray patch, for uses requiring neutrals-only to be
