They are a couple of shades darker than that. The enamel itself is a blueish white colour, but it is also somewhat translucent so the yellow of the dentine beneath it shows through to make the overall colour of the teetheither light grey or light yellow.

Teeth have different layers that give them the appearance you see on the outside. The outer layer, known as the enamel, contains a component of calcium, which tends to be white in color. But, the whiteness of enamel is sometimes out of your control. Some people are born with whiter, thicker enamel and may simply be blessed with great looking teeth. This is not necessarily an indication of how healthy teeth are: it’s just genetics.
Beneath the enamel lies the dentin, or the which is usually yellowish. If the white enamel gets thinner with time, more of the yellow dentin will show through — and teeth look less white overall.
To help keep teeth looking youthful and white, treat enamel with care so it stays thick and healthy. Brush gently with a soft toothbrush twice daily, floss, and see your dentist every six months. Also pay attention to acidic foods and drinks such as coffee and citrus fruits. These can wear down enamel over time, especially if you brush teeth vigorously right after consuming them.
If you were born with less-than-white teeth, there is hope! Your dentist can talk with you about whitening options that may correct the issue. In addition, porcelain veneers are an excellent option for people who have discoloration or cosmetic issues.
