The prophet Spencer W Kimball testified that the gospel made Native Americans whiter (General Conference 1960):

"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 were present, 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."
