They are usually in all colors but some can be bought in black and white. What a wizard likes to do best depends on what they like to do. What they like to do comes from their mind. Some wizards will be adventurous, some will be naughty, some will be clever. But I guess any wizard would like just waving their wand around.
Wizard minds work differently from muggle minds, as their world is more ordinary, more dull.
They do not believe in the wizarding world. They do not believe in magic and excitement. So the muggle mind thinks differently from the wizard mind because both minds cope with different things. I think the most intresting thing in my muggle town whould be skateboarding. This is what I think would find most interesting about my home town.
