For example, if you want to create an e-commerce website selling toys, you'll not use black because it suggests something more classy and elegant. You will use it more on a luxury brand such as L'Oreal or MAC Makeup:

See how L'Oreal uses the black color to look more luxurious even though they are not in the market for luxury. 

Of course, remember that these are just guidelines (they always depend on context). Take a look at different websites and see how they use colors, it's always the best way to learn.
