The solution would turn from blue-green to blue, then to pink.
Key Takeaway: Sodium hydroxide has a pH of around 10, which would change the pigment to a blue-green color. The major component of vinegar is acetic acid, so adding that to the solution containing sodium hydroxide will lower the pH. The color will in turn change from blue-green to blue, and ultimately to pink.
