Yellow

Explanation:

Thymol blue has a brownish-green or reddish-brown color and is a good pH indicator. It changes from red to yellow at a pH 1.2-2.8 (acidic) and then from yellow to blue at a pH of 8.0-9.6 (alkaline).

Nitric acid is a strong acid which means the pH indicator will change to yellow.
