The colors in these curtains are beautiful and very vibrant. Greens and blues are the primary colors, but there is also a little yellow paisley design worked in with the flowers and leaves. The only reason I rank these curtains 4 stars instead of 5 is because they were much thinner than I expected. They do block some light - they are definitely not sheer- but I would not call them "room darkening." I will probably add another layer of lining for the window that gets a lot of sun.
