This is part of my ongoing Letter Series.
Rules:
Standard sudoku rules apply.
Entropic Lines: For digits along tan lines (the outer enclosed line of the C shape): any three sequential cells along it must contain one low digit (1, 2, or 3), one middle digit (4, 5, or 6), and one high digit (7, 8, or 9).
Dutch Whispers: Digits along orange lines (the inside line within the C shape) must differ by 4 or more.
Kropki dots: Digits separated by white dots are consecutive. Digits separated by black dots must differ by a 1:2 ratio (one is double the other). Not all dots are given.

Loved the solving logic.
Might be rather difficult for the colorblind.
