A whippet might work well for you - though I am very biased when it comes to sight hounds! they are medium sized dogs and though they tend to be couch potatoes inside they are up for doing whatever you want. They are short haired, come in many different colours, and tend to be quiet.
another option might be a Cardigan Welsh Corgi - they have a higher energy level than a whippet but I know quiet a few people who keep them in apartments. They generally enjoy playing games and fetch. They do not come in pure black but they do come in black and white and tri-colour.
