Im pretty sure its just opposite colours of normal parakeets.
A male parakeet has a blue nose above its beak.
what is the difference between honeybee and blue Jay
The difference between the green and blue kyanite is their colors.
basicly except 4 the fact they are different colors.
Generally, a male Bourke's parakeet has a blue forehead and the female lacks the blue coloring. Males are also larger than females.
This cannot be answered simply, because there is actually no specific breed of bird called a "parakeet". The term "parakeet" is a generalised term to cover numerous species of smaller, long-tailed parrots, specifically budgies, lorikeets or cockatiels. If you are really talking about budgies, which is the bird most commonly referred to in the States as a "parakeet", then a mature male tends to have a deep blue cere, which is the waxy bit above the beak where the bird's nostrils are. Males only develop this blue as they mature towards repreoductive age. Females have a white cere but, when they are in breeding season, it deepens in colour to brown.

a boy.
white with some blue
The spelling
I don't think so. I read that adult female parakeets noses are brown and that adult male parakeets noses are blue. But, young female parakeet's noses are "bluish" and a young male parakeet's nose is pink.
It is blue
