Thanks for your thought and true, the name isn't everything. But I think that a good name sure helps, especially when it comes to marketing. Color probably get a lot of traffic from being nr #1 on Google search for "color", but if you don't want to spend huge amount of money, colorapp.co or colorapp.com would probably work great as well. My point is, the name matters and adding two or three letters to a good name is better than having a short and snitzy but hard to spell name.
