J.M.W. Turner is strongly light-biased - shadow is suggested rather than declared. J.M.W. Turner keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. 26.6% of the palette belongs to #DDDAC8, a concentration that makes it the unmistakable visual centre. The highest-chroma note - #4D5487 - appears at just 3.8%, deployed as a precision accent against the quieter ground. The full value range is 63 units: broad enough to build convincing three-dimensional form. In the context of J.M.W. Turner's full range of palettes, group 7 represents one movement in an ongoing chromatic dialogue.
