How to say "aqua" in Japanese

• 水色みずいろCommon
  no-adjectiveThe everyday word for the color: a pale, light blue — the shade English calls aqua. Use it when simply describing something as pale blue, such as water, the sky, or clothing.
  頭上ずじょうの空そらは濃こい水色みずいろだった。↗

  The sky above was a deep blue.
• アクア
  nounThe loanword, borrowed straight from English aqua. It appears where the English term itself would — in product names, color charts, and design — not as the ordinary word for a pale blue.
• 青緑あおみどり
  no-adjectiveA color word for the shade between blue and green — blue-green or turquoise, the greenish sense of aqua. Choose it when the color you mean is greenish rather than a pale blue.
• 青緑色せいりょくしょく
  no-adjectiveThe same bluish-green shade as 青緑, in its fuller form with 色 'color' attached — an explicit color name for the turquoise/aqua hue. In most contexts it overlaps with 青緑 rather than differing in meaning.

Use 水色 for the everyday pale blue that English calls aqua; 青緑 and 青緑色 name the greenish turquoise shade; 「アクア」 is the borrowed English word, found mainly in names and design contexts.
