There is no specific color they like better over all. It may just differ from bird to bird what colors they like best, as parakeets can actually see more colors than we can!
There is nothing about parakeets' color that relates to their personality. It is how they are raised and tamed that matters!

NO.....It is believed that parakeets can see in color just as humans do. All members of the parrot family are able to see in colour. The males are more colourful in order to attract the females. Also, they can see the bright colours of the flowers on which they often feed.
Depending on your Parakeets color, it's perfectly normal for parakeets to not have blue on it's head...
In short, yes. The key is can those two specific blue parakeets get along. Color doesn't matter, but the two parakeets personalities may clash. If you have had a parakeet for a long time, he may not take kindly to an intruder. Often if you have three, two will bond and pick on the outsider. It is really about the individual birds not the color.
