Welcome to the forums!
There are 3 distinct colour mutations that render a budgie's plumage fully white.
Albino budgies are fully white in colour, have pink feet and red eyes, there is no mistaking.
White based (blue series) dark-eyed clear budgies are fully white in colour, their eyes are black in colour and due to the combination of genes, these budgies will not develop white irises upon reaching adulthood. Their feet are pink in colour.
The ceres on male dark-eyed clears and albinos will not mature to the royal blue colour. The ceres will keep the pinkish/purplish colour.
White based (blue series) double factor spangles are also fully white in colour, their eyes are black in colour and they will develop white irises upon reaching adulthood. When mature, the ceres will be royal blue in colour.
Depending on the chick's heritage, there can be some faint suffusion of blue colour on the feathers, especially when under certain lighting.
Just like with canaries and other species of pet birds, it's also not advisable to breed two visual Ino (albinos, lutinos) budgies.
It would be best to find a normal blue series budgie who is split for Ino to pair with a visual albino.
