The Hebrew that is translated with “ruddy” in English is translated in Mandinka as “light-skinned.” “‘Light-skinned’ could be considered a cultural equivalent. Although there are a few people with reddish skin in Mandinka, this is not an attractive trait. The UBS Handbook (A Handbook on the First and Second Books of Samuel by R.L. Omanson and J. Ellington) suggests that ‘ruddy’ may have referred to the hair, but medical people know that reddish hair is a sign of malnutrition.” (Source: Rob Koops)
In Vidunda it is translated as “healthy/strong” and in Kwere as “powerful” (source: Pioneer Bible Translators, project-specific translation notes in Paratext).
