🟢🌿 绿 = 糹(silk) + 彔 (phonetic, like 录) — silk dyed green
The 糹 radical marks textile/dye words; 彔 gives the sound (compare 录 lù, 禄 lù). 绿 originally described silk dyed a fresh green colour, then broadened to mean green in general.
绿 — silk radical 纟 + 录 (phonetic)
绿 is a phono-semantic compound. The silk radical 纟 (糸) signals the original sense of a dyed silk color, while 录 supplies the sound. It came to mean the green color produced by such dyes, and now refers to green in general.
