A bipartite stimulus 2 degrees in diameter was used to study the Bezold-Brücke phenomenon for purple colors. A mixture of 460 nm and 667 nm in one half at a given luminance was matched with a mixture of the same two wavelengths at a luminance level 10 times higher. The hue of the 667-nm stimulus was not affected by the change in luminance. There is one mixture of red and blue which remains unchanged in hue as the luminance increases. Reddish purples shift toward red and bluish purples toward blue. These findings are consistent with a zone theory of color vision such as proposed by Adams.
使用直径为2度的二分刺激来研究紫色的贝佐尔德-布鲁克现象。在给定亮度下，一半由460纳米和667纳米混合而成的光，与相同两个波长、亮度高10倍的混合光相匹配。667纳米刺激的色调不受亮度变化的影响。存在一种红色和蓝色的混合光，其色调在亮度增加时保持不变。偏红的紫色向红色偏移，偏蓝的紫色向蓝色偏移。这些发现与亚当斯提出的颜色视觉区域理论一致。
