Yes, a goldfish can see you; in color for that matter. Goldfish have eyes on the sides of their heads which gives them a blind spot right in front of them. They can see fairly decent close up but not as clear at greater distances.
They can also sense your movements with their 'sixth sense' located in their lateral line. It helps them recognize where predators are approaching from.
