Its difficult to tell as they aren't standardised examples of the colour.
The mother looks to be red eyed (although it might be the flash) she could be a fawn, argente, cinnamon or possibly a champagne, but it would be a very dark champagne. The colour looks too even to be an argente or cinnamon I cant see any ticking. So could be a fawn which I know very little about although the third baby looks the same as the mopthe.r The other two babies look like doves to me, probably not lilacs as they red eyes.
What is the dad?
