which is the most reactive form of phosphorus?

Question

blue, red, white or black? or are they all equally reactive?

I suppose its a matter of how you define reactive but I would go with white since that reacts at room temperature with oxygen of the air to creat heat and burn whatever it is touching. I didn't know there was a blue allotrope. Black, white (yellow), red are the ones I know. I believe the black one may be the same as the blue since literature describes the black as (black/violet).

its deff white
