ID Please My moms Iris's

This is one of the several Iris's my mother gave me that are over 10 yrs old. Could anyone please help me with the name of this particular one. It seems to be white but does have a slight hint of blue or purple to it.

Thanks!

Pic is a little out of focus but try 'Silverado'. It will have a silver-blue tint.

your right I didn't realize it was blurry. The silverado has the purple tint and I think mine is more blue tint. I will try to get better pic tommorow. Thank you for your help!
