I really can't offer a very deeply informed opinion. As you probably know there is already a college tv group and at least one YouTube channel on teal. I searched NameBio and found some two word colour sales, but in at least what I searched could not find close comparator sales. I am told that blue and green are for most people (at least in North America) so a colour mixing those has potential. I see that it would work well for a business in wedding or prom dresses, or more likely an aggregator fashion site. Best wishes for it. With only 4L and with .tv continuing popular, I see some definite plusses.
