Hues for probed stimulus pairs within and across the English green-blue boundary for Study 3, from Table 1 of Roberson and Davidoff (2000).

Any stimulus pair that includes a boundary color is considered to be a cross-category pair. All hues are at value (lightness) level 4, and chroma (saturation) level 8. 1s denotes a 1-step pair; 2s denotes a 2-step pair.

所有包含边界色（boundary color）的刺激对（stimulus pair）均被视为跨类别对（cross-category pair）。所有色相的明度（lightness）等级均为4，彩度（saturation）等级均为8。其中1s代表1步配对（1-step pair），2s代表2步配对（2-step pair）。
