Unfortunately, its a little worse than that, Camter.
See, we've already seen and experienced chess.com on v2.
If we hadn't already had that, then yes, we can choose any color we want as long as it's v3. That's the problem.
The 2nd challenge facing Erik and his staff is the other old adage of IT---don't over-promise. v3 was given all the Pomp and Circumstance & Ode to Joy reprises as the End All to Chess Sites of the internet. Problem is, .. it just has the wrong framework underlying the whole thing to accomplish such. And, as is, v2 is simply (emphasis on simply!!) a better platform for this site.
We all see it as such. We can see the effort put in to v3, as well. But, as customers, many of us simply prefer to interface with the site in v2. And, as a business person, I can understand it completely.
My customer base wants v2, by golly, I will continue to sell them v2 until I convince them v3 really is a better deal: for them, and for me.
If I were Erik, the solution would be an easy one: tell the Dev team to take a hike in to the deep mountains and don't come back until they truly have a better product for the customer base to accept.

The other ten we are just stuck with. 
I hope V2 gets an extension until V3 is faster and bug free!
Possibly. Still discussing options.
This shows that you are aware of the problems of the end-user, that horrible creature which does not praise you for your successes, but never fails to point our where you have not got the job done to its liking.
It is that thing which any CEO must have, the realisation that customer relations are everything in business. "The customer is ALWAYS right" was drummed into my head by my small business father, who then would privately tell me that they were not actually, and were a right "pain in the neck".
Such is the price of business success, and prudent compromise is an important part of it.
Ford's dictum, "They can have any colour they like as long as it's black" worked for a while perhaps, (and I doubt if he really ever really embraced it), but today would spell disaster.
