Alno carries a color called Pewter, kind of stainless - gun metal gray. You should consider this option.

i like the idea of doing a matte black. we did chrome when we redid our kitchen a couple years ago and i always play with the idea of ordering the same pulls in matte black for a change.

I like stainless pulls but I really dislike all pulls the same size since a 5” pull on a 30” wide drawer looks pretty silly not to mention you would need 2 which is never good. So without seeing the actual layout it is hard to make any other suggestions but I like pulls to be in proportion to the cabinets fronts like this. I also love the stainless bar pulls from Lee Valley that come in tons of sizes .
