Lavender/gray feral pigeon?

Feral pigeons flock to my bird feeders, one is very odd colored. Its a grayish-lavender, some in its flock are the "typical" gray/blue pigeon color so you can see how light this one is. It even has an orange beak when normally only white pigeons have that, usually beaks are black. Ive never seen one in this color before in the wild, only selectively bred in domestic birds and that is rare to get, and this is clearly wild. I guessed on the color description I dont even know the correct term/morph. If they look wet it was raining out.
