My Budgie is a color shifter

[patsoxfan00]

My Female Budgie Coconut is a year old now, and since having her we notice that she goes from completely white to suddenly her feathers turn green and ocean blue when out having fun . Her back changes from oranges to red to pink her checks flutter like a disco ball in light. But when she returns to her cage she becomes solid white all over. she is like one of the stones that change color with heat. has anyone ever heard of this ?
