An amazing color discovery

I have had this iron patio set with the rust cushions for 7 years. I really want to recover the cushions to go with my updated palette of creams and grays, a touch of black, and aqua blue.  My budget, however, is not agreeing with my decor plans.

How can rust work with my new colors?

I found these two (alas, only two) outdoor pillows on clearance at Home Depot.  The background is a muted blue with a floral pattern that has just a touch of rust!

Today, Nester's post on her Salvation Army find affirmed my amazing color discovery and now I am happily putting off the upholstery update until next summer.

Here is a great photo I found on Pinterest featuring aqua and rust (real rust even!).
