I chose the color called "pearl" which looked online like an off/white, but it is actually a light gray.  It worked for my room anyway.  It really blocks the light from outside, and the sun/heat.  the liner is black, if that's a problem for anyone.  I had to use my electric hand steamer to remove all the lines and wrinkles.  For the price, they look very nice, and do the job for blackout.
