Chlamydomonas nivalis (which is not a flower as announced). This is a picture of a snowball suitable for throwing. It's colored by a microorganism, commonly classified as a green algae, which often tints patches of the melting mountain snow with this purple-red color. Being it its dormant state, chlorophyll is temporarily absent and its content of hematochrome determines the color.
