my fittonia turned pink 😅

This is my red veined fittonia (I’ve had this since january 10) and today, I noticed it turned pink in color. Is this normal?

I used to keep it in my bedroom with morning sun only but I decided to leave it outside in the balcony (Morning Sun + Bright Indirect Light) and I noticed it grows faster! I mist it daily as needed. The soil mix I use is coco coir and vulcanized rice hull.
