This is not an albino because it has green leaves and green flower parts. A true albino would lack chlorophyll and would probably not survive long enough to flower. It's probably a white variant of red clover or a similar white clover growing among the red plants.
Sorry for my ignorance and thank you both for the correction and learning. Yeah, it must be a white variant of red clover then. It is definitely not a white clover. Hope at least the picture is nice.
