Fifty Shades of Grey ⇥ 9to5mac.com

To be fair, Michael Steeber of 9to5Mac has catalogued only twelve shades of greys and blacks that Apple has used since 2012. Several of those variations show very minor differences; I wonder if the shades of white and even the plain anodized aluminum shades Apple has used over the same time period also show similar — albeit more subtle — variations in colour.
