• CIE 15:2004 names the blue region as the site of CIELAB's residual non-uniformity, and states the CIEDE2000 rotation term exists to correct it

• Sharma, Wu & Dalal (2005) locate the CIEDE2000 blue-region rotation term's impact near a hue angle of 275°

• Urban, Rosen, Berns & Schleicher (2007) is reported to state that non-Euclidean CIELAB-based color-difference spaces have regions of nonzero Gaussian curvature obstructing isometric embedding — not yet quote-verified against the primary

• Capture: CIELAB's perceptual-uniformity design intent and blue-hue shortfall, verified against the primary CIE technical report

• CIELAB is only approximately perceptually uniform, and the historical fix was non-Euclidean colour-difference formulas culminating in CIEDE2000
