Angie has several ensembles that combine leopard print or cognac with greys and I think you will see a range. I actually like the warm tones as a "pop" against the cool and with your blonde hair, leopard bookends/ or ties together. I used to ADORE leopard print (warm ones) for that reason alone. If I wore a leopard shoe or belt (or bag) it automatically looked cohesive with just about anything, due to my hair.
Now with my grey hair, I have to be more careful and deliberate about it since I have no warm tones. It's an addition and the leopard needs a strong dose of black, blue, charcoal, or white for it to work.
