I don't have reliable information about a specific artwork titled "Eden, Colo." by Art House: The Collection of Chara Schreyer in my training data. To provide you with accurate, factual details about this work, I would need to verify its details through a museum collection database or other authoritative source. I'd recommend checking the collection directly or contacting the institution that holds it for accurate information about the artwork's medium, dimensions, date, and artistic significance.
