Several Book of Mormon passages have been interpreted by some Latter Day Saints as indicating that Lamanites would revert to a lighter skin tone upon accepting the gospel. For example, at a 1960 LDS Church General Conference, apostle Spencer W. Kimball suggested that the skin of Latter-day Saint Native American was gradually turning lighter:

"I saw a striking contrast in the progress of the Indian people today. ... The day of the Lamanites is nigh. For years they have been growing delightsome, and they are now becoming white and delightsome, as they were promised. In this picture of the twenty Lamanite missionaries, fifteen of the twenty were as light as Anglos, five were darker but equally delightsome. The children in the home placement program in Utah are often lighter than their brothers and sisters in the hogans on the reservation. At one meeting, a father and mother and their sixteen-year-old daughter we represent, the little member girl – sixteen – sitting between the dark father and mother, and it was evident she was several shades lighter than her parents – on the same reservation, in the same hogan, subject to the same sun and wind and weather. ... These young members of the Church are changing to whiteness and to delightsomeness. One white elder jokingly said that he and his companion were donating blood regularly to the hospital in the hope that the process might be accelerated."

Mormons are disgusting
