I like the new colours better. I have seen the 747-400, 737, and 767 in the new colour scheme and it looks quite nice.
The new blue is not dark (or even black!). It's waaay lighter than it appears. The blue does look dark in internet and magazine photos though. The red 'Canadi>n' stands out more than the old blue, and is larger. But it's not that huge (only one the 747). It is quite small In general, the new look is brigher.
