ONCE colours?

Why are team ONCE sometimes in pink and sometimes in yellow??

 

The Tour directors let ONCE wear yellow for the time trials but insist on some other color for the other stages so no one would mistake an ONCE jersey for THE yellow jersey. ONCE picks pink but there have been other teams that have had alternate colors.

 

Thanks that makes alot of sense. What is the go with Vini Caldirola then? They look like a team of yellow?

 

Once was a doped sqaud too!
