Ive raised archangels by hand and they always end up being skittish birds. I dont breed them anymore for that reason. They are beautiful but i dont think they are the most tamed breed.
If you want a more tame or gentle bird, german owls or chinese owls are a good way to go. They are white birds though but have other colorings in them. But they are known to be the more submissive, docile breeds.
They are great starter birds!
If you prefer darker colored birds, rollers too are lots of fun and they are easy to handle. But they can be hard to come across because not all of them are proven rollers, many people lie about having rollers and end up being homers or tumblers. So get rollers from a reliable source.
Really any bird can be a friendly bird, it all depends on how much time and love you give it. Adults are harder to get them to like you, unlike raising it yourself then it imprints on you and you got a bestfriend for life instantly.
Ive bought many grown birds that now come and fly to my hand and love to be given attention and love, but it took lots of effort to get to that stage with them. They will learn to trust you.
Many people have lots of white birds and fly them with no problems from hawks. Most pigeons out fly hawks and falcons. Pigeons are very fast flyers.
As long as you give them the right amounth of protein in their feed, and fly them regularly, your birds will be tough as nails and be great flyers!
A hawk, owl, falcon, etc... will always go after your birds wether they are white or dark coloered birds. These predator type birds have such great eyesight and hunting skills that they will spot out your birds no matter the color. If they can spot a little brown mouse in a field, they will spot out your birds wether they are white, brown, black or multicolor.
If you feel nervous about flying them you can always just make a bigger flight pen for your birds. Or what i do is i just keep a pellet gun when i fly my birds and let my roosters out, my roosters alert me when a predator is flying and i will shoot the bird with the pellet/BB gun. It doesnt kill or injure the hawk, but it does give it a nice sting and scares it away. You can always use a sling shot too if you dont have a BB gun.
I hope all goes well and im excited for you wanting to get your loft started up and getting some birds! If you have any questions feel free to ask me anytime!
