tale of two fabrics

after much internet research, finally found background for my "midnight at the oasis" at a good price....it was labeled as a gray with white polka dots.  see retailer's swatch below...

looks gray too, doesn't it?   you can imagine my dismay when what arrived was tan with neutral polka dots....not gray at all and no white dots either.  before contacting retailer, decided to take a photo of the wrong fabric for comparison....

again dismayed to find there is little noticeable difference between the two when photographed.  the only thing in my favor, i would think, is that the retailer lists the fabric as GRAY, in with its black/gray fabrics.  not tan, not beige, not toast, not brown or any other variation.  it's a lovely fabric and i would keep it if the retailer sends me the gray no charge (who wouldn't?)...it would make a nice background for another project.  but i'm hoping the retailer will send me the gray as that is what i originally selected.  true, i'll live just as long if i HAVE to use the tan, as the budget just can't fit in another 3 yards right now, and it is really small stuff in the grand scheme of things.  nobody will suffer some horrendous calamity and it isn't even a blip in anyone's life.  i'll let you know how it turns out....either way life will go on pretty much the same, which is certainly good enough.
