There is no universal "sexy" hair colour. Hair colour is a personal preference. Your hair colour should be a similar shade to your eyebrows and should compliment your eyes. Ask a professional hair stylist what colour suits you.
It should turn the UI to a light yellow because it is a very mild acid. It has a pH level of around 6. Whereas a strong acid like Battery Acid (pH 1) would make it a red.
red cabbage is a good universal indicator you need a red cabbage hot water and a pestle and mortar put hot water into the mortar and crush the red cabbage leaves with the pestle the water should turn purple. your own universal indicator!
