インナーカラー

• Reading: インナーカラー
• Romaji: innā karā
• Pronunciation: /iɴ.naː ka.ɾaː/

Meaning

Inner colour; a hidden layer of dyed hair underneath the top layer, creating a peek-a-boo effect.

インナーカラー is a hair colouring technique where the inner layers of hair are dyed a different colour (often vivid colours like pink, blue, or purple) while the outer layer remains natural or dark. This creates a subtle reveal when hair moves or is tied up. It became extremely popular in Japan because it allows for self-expression while remaining work-appropriate — the colour is hidden under normal circumstances. It is a perfect compromise for people in conservative workplaces who still want fun hair.
