📺🌈 彩 color + 电 electric = color electric screen, a color TV
彩 (cǎi) means colorful or multicolored, 电 (diàn) means electricity or electronic. Together they literally say colorful-electric, distinguishing a color set from old black-and-white TVs.
电 — rain 雨 + lightning tail 电
Originally a pictograph of lightning streaking from a cloud, written 電 with the rain radical 雨 on top. The bottom 电 depicts the zigzag flash itself. The simplified form 电 drops 雨 and keeps just the lightning shape. Meaning extended from 'lightning' to 'electricity' in modern usage.
