The Abney effect states that desaturation of spectral colours does not only change their chromatic saturation but also their hue. By means of Hering's perceptual criteria "neither blue nor yellow" and "neither green nor red" and heterochromatic brightness matching, chromaticity loci were measured in a visual tri-stimulus colorimeter; the loci served for construction of an opponent-colour triangle and the associated opponent-colour space. The chromaticity line resulting from the perceptual criterion "neither green nor red" deviated markedly--as an expression of the Abney effect--from a straight line. This phenomenon was captured by piecewise linearizing. The transformation of the (known) fundamental colour space, which may be interpreted as a cone excitation space, onto the opponent colour space thus gained yielded an explicit opponent-colour theory that reproduces some aspects of the Abney effect.
阿比尼效应表明，光谱颜色的去饱和不仅会改变其色度饱和度，还会改变其色调。借助于黑林的感知标准“非蓝非黄”和“非绿非红”以及异色亮度匹配，在视觉三刺激色度计中测量了色度位点；这些位点用于构建对立色三角形和相关的对立色空间。由感知标准“非绿非红”产生的色度线明显偏离直线——作为阿比尼效应的一种表现。这种现象通过分段线性化得以捕捉。将（已知的）基本颜色空间（可解释为锥体激发空间）转换到由此获得的对立色空间上，从而产生了一种明确的对立色理论，该理论再现了阿比尼效应的某些方面。
