Pearl (keycap)
Provided by the ASK Keyboard Dictionary
"Pearl" in a keycap context was IBM's, Lexmark's, Unicomp's and TGCS' term for a chromatically-warm white colour. Pearl keycaps are typically paired with pebble keycaps as part of a two-tone set, with pearl keys usually being alphanumeric and the spacebar and pebble keys usually being arrows, enters, modifiers and operators. They are typically found on IBM and family pearl white keyboards.
