I got the grey colour, it matched my walls perfectly and I am very happy with them. They are just what I was looking for at a great price. I wouldn't call them blackout, but room darkening. This picture is taken on a cloudy day, I'd imagine when its sunny you will be able to see through them a lot more.  The grey colour on the listing photo looks like a light grey, it is definitely more of a medium grey. I have attached a second picture to show the curtains next to a light grey pillow I have for reference.
