Surveys that assess skin color support evidence building about colorism and related systemic inequalities that affect health and wellbeing. Methodologists have increasing choices for such assessments, including a growing array of digital images for rating scales and increasingly cost-effective handheld mechanical devices based on color science. Guidance is needed for choosing among these growing options. We used data from a diverse sample of 102 college students to produce new empirical evidence and practical guidance about various options. We compared three handheld devices that ranged in price, considering variations in their reliabilities and how their results differed by where on the body and with what device settings readings were taken. We also offered evidence regarding how reliably interviewers and participants could choose from a large array of color swatches offering variation in skin undertone (redness, yellowness) in addition to skin shade (lightness-to-darkness). Overall, the results were promising, demonstrating that modern handheld devices and rating scales could be feasibly and reliably used. For instance, results demonstrated that just one or two device readings were needed at any given location, and, the device readings and rating scale scores similarly captured the relative darkness of skin. In other cases, recommendations were less certain. For instance, skin undertones of redness and yellowness were more sensitive to device choices and body locations. We encourage future studies that pursue why such variability exists and for which substantive questions it matters most.
