皮肤颜色的反射分光光度法测量134对双胞胎在3个地点，前额，前臂和上臂，每个在3个波长，425，545和685 nm。在685 nm处测量晒黑最可靠;在该波长处，在暴露最少的上臂部位（前臂上的中间部位）的遗传性高，而前额上的变化完全由环境决定。在545 nm处也观察到同样的梯度，尽管不太明显;在425 nm处，血红蛋白反射大部分光，遗传决定的程度在所有位点都是相同的。
Skin color was measured by reflectance spectrophotometry on 134 pairs of twins at 3 sites, forehead, forearm and upper arm, each at 3 wavelengths, 425, 545 and 685 nm. Tanning is measured most reliably at 685 nm; at this wavelength the heritability is high at the least exposed upper arm site, intermediate on the forearm, while on the forehead variation is entirely environmentally determined. The same gradient is observed, although less strikingly at 545 nm; at 425 nm, where Hb is reflecting most of the light, the degree of genetic determination is the same at all sites.
