Color appearance can be specified by a procedure of direct hue and saturation scaling. The scaling data can be represented on a 2-D color space termed a uniform appearance diagram (UAD). The orthogonal and bipolar axes of the UAD are based on the four unique hue sensations, which are blue-yellow and green-red. We have previously shown that the technique is reliable and rapid. We now show that the UAD is sufficiently uniform metrically that it can be used to derive, from a single set of scaling data, a wide range of color functions, such as the spectral loci of the unique hues, wavelength discrimination, and similarities among very different colored stimuli. The advantage of deriving a UAD is that it requires only a modest amount of participant time to generate the relevant data, which can be re-generated quickly to meet changing viewing conditions.
颜色外观可以通过直接色调和饱和度缩放程序来指定。缩放数据可以表示在一个二维颜色空间上，称为均匀外观图（UAD）。UAD的正交和双极轴基于四种独特的色调感觉，即蓝黄和绿红。我们之前已经表明该技术可靠且快速。我们现在表明，UAD在度量上足够均匀，以至于它可以用于从一组单一的缩放数据中导出广泛的颜色函数，例如独特色调的光谱轨迹、波长辨别以及非常不同颜色刺激之间的相似性。推导UAD的优点是，生成相关数据只需要参与者花费适度的时间，并且可以快速重新生成以满足不断变化的观看条件。
