Modern Japanese usually distinguishes:
緑 (midori) — green
However, the traditional range of 青 included some greenish shades and the fresh colors of plants. That older range remains in established expressions.
青葉 — fresh green leaves
青草 — fresh green grass
青菜 — leafy green vegetables
青りんご — green apple
青虫 — green caterpillar
Learn the older ao expressions as complete vocabulary items.

Why Are Green Traffic Lights Called Ao in Japan?
The Japanese term for the green “go” signal is 青信号 (ao shingō), literally “ao signal.” Its natural English translation is green light.
Shingō ga ao ni natta.
The traffic light turned green.
The name survives because ao historically covered part of the blue-green range, 青信号 became a fixed expression, and Japanese traffic terminology officially uses 青.

What Does Murasaki Mean?
紫 (murasaki) is the ordinary Japanese word for purple, but its history begins with a plant.
↓
purple dye made from its root
↓
the color name murasaki

associations with high rank, refinement, and classical culture

Common Beginner Mistakes
Mistake 1: Adding い to Every Color
a red flower
× 緑い花
Not standard Japanese
○ 緑の花
a green flower
× 紫い花
Not standard Japanese
○ 紫の花
a purple flower
Mistake 2: Calling Every Green Object Ao
青 refers to green only in certain established expressions. Use 緑 for an ordinary green object.
Mistake 3: Translating 青信号 as “Blue Light”
The natural English translation is green light.
Mistake 4: Treating Traditional Color Names as Exact Universal Codes
The appearance of a named color can vary by material, dye, period, source, lighting, and color standard.
Mistake 5: Assuming a Color Has One Permanent Cultural Meaning
White can appear at weddings, shrines, and funerary traditions. Black can express mourning or elegant formality. Context matters.
赤・青・黄色・緑・紫・白・黒・茶色・ピンク・オレンジ
Then learn which ones use 〜い, and add traditional shades gradually.
