well she is a peach face for sure, thats her species, but no lutino. lutinos have red eyes and absolutely no green or blue pigment. lutino happens when they lose all melanin but still keep the other pigments. happens the same with cockatiels, macaws, kakarikis, etc. thats why they have red eyes--lack of melanin even in the eyes as well. lutino lovebirds will have a white rump, and they will have red streaked tail feathers and a red (or orange face if an orange faced peach face) face. but never a speck of green. if they have a blue rump or any green on them at all, even one feather, they are a pied.
lutinos can also be "parblue" mutations (seagreen, whiteface, and dutch blue). these are called creamino. instead of having a red face like a "green" lutino, they have the mask like a parblue mutation, which is a diluted version of the wild green colour.
personally, pieds are my absolute favourite mutations in lovebirds. also, fun fact--munch is actually pied--she has a couple flight feathers with pied mottling! genetically, it makes her a pied.
