Paire de rideaux obscurcissant Weston (Ensemble de 2)

I ordered these curtains with matching bedding in September for a remodel job that got pushed out til January. I just opened everything up and got them set up in my bedroom and I am not happy with the results. The curtains don’t match the comforter. They are much darker. They look almost dark olive green instead the silver and blue of the bedding. According to your return policy, it’s too late to return them even though I have just now opened all the packages after 4 months. I paid a lot of money for this set and would like to work out a solution if you are willing. I love the bedspread, but the curtains look awful with it.
