Most Goths love black.
You can see that again in their make-up-up, which is often black in combination with a white face.
The hair is usually also black, but actually anything goes in the Gothic-scene as long as you feel comfortable.
It is worth your while watching Goths at meetings.
At gothic festival you often see the most beautiful creations; however in every day life many Goths limit themselves to what is “socially acceptable”. 

Often it is difficult to find good make-up.
White powder and black eye shadow can usually only be bought at party shops or around Halloween.
