The spectral sensitivity at the opponent stage of the visual system is traditionally measured by a hue-cancellation procedure. Comparison with a direct hue-matching method shows that cancellation overestimates short-wavelength sensitivity by as much as a factor of 30. The observation implies that different mechanisms control the perception of short-wavelength and long-wavelength redness.
视觉系统拮抗阶段的光谱灵敏度传统上是通过色调消去程序来测量的。与直接色调匹配方法的比较表明，消去法高估了短波长灵敏度，幅度高达 30 倍。这一观察结果表明，控制短波长和长波长红色感知的机制是不同的。
