脚 — meat radical 月(肉) + 却 (phonetic)
脚 is a semantic-phonetic compound. The left side 月 is the 'flesh/body' radical (from 肉), marking it as a body part. The right side 却 supplies the sound. Originally it referred to the lower leg or shin, and later broadened to mean 'foot' or 'leg' generally.
色 — person 人 (top) + kneeling figure 卩 (bottom)
Originally a pictograph showing one person above another, traditionally interpreted as depicting facial expressions or intimate posture between two people. The earliest meaning was 'facial expression' or 'countenance,' which extended to 'appearance' and eventually 'color' (the look of things). The 'shǎi' reading is a colloquial variant used for everyday color words.
