• 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

• CIE 15:2004 states CIELAB was recommended as a perceptually more uniform alternative to CIEXYZ, in the CIE's own words

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

• 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

• CIELAB (1976) was built to fix CIEXYZ's perceptual non-uniformity — and still falls short of its own goal, especially in blues

• CIELAB (1976) was designed as a perceptually uniform color space to remedy CIEXYZ's perceptual non-uniformity

• CIELAB fails its own perceptual-uniformity goal, most notably in the blue hues
  claim budding Tier 4 2026-07-09 · color-science, cielab, colorimetry, perceptual-uniformity, hop
• Verify against a primary CIE / colorimetry source: (a) that CIELAB (1976) was designed for perceptual uniformity, and (b) that it is known to fall short particularly in blue hues
