五颜六色

multi-colored
🌈 五颜六色 = five colors + six colors (idiom for every hue)
Literal breakdown: 五 (five) + 颜 (face/color) + 六 (six) + 色 (color). Chinese idioms often pair numbers like 五/六 or 三/四 to mean 'all kinds of'. So 'five-color six-color' = the full spectrum.
五 — two horizontal lines + crossed strokes
五 originally depicted two parallel lines (heaven and earth) with an X between them, representing the interaction of the five elements. Over time it became the standard numeral for 'five.' The ancient form 㐅 (just the X) was later framed by the two lines to distinguish it clearly as a number.
六 — top stroke 亠 + 八 (eight/split)
Originally a pictograph, possibly depicting a hut or shelter, but its early meaning was lost. It was borrowed phonetically to write the number 'six'. The modern form shows a top mark 亠 over 八, but this structure is not semantic — it's purely a loan character for the numeral.
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.
