I like #2 and #3.

Changing the blinds might be needed lol cause i like the cream too. It is a very plain room but i like simple rooms for sleeping.

My husband likes the monochromatic look of two. I lean to natural linen or cream. AI likes oatmeals and creams best.

I agree with your DH the blinds and drapes look good in a cohesive color. Is the stripe on the Duvet cover also a charcoal grey? It is a pretty room and I love a serene setting for sleep. My bedroom walls are about the same color as yours .c

With the gray shades I like the drapes also in gray.

The stripe is charcoal and the bathroom tile is a grey herringbone so lots of blue and grey.

I like the cream a lot.

I don't love the cream drapes and gray blinds together.

I also don't love the gray blinds with the blue wall color.

For me, something has to go, and my gut reaction is the gray blinds.

Unless you love the gray blinds ... don't keep throwing money into that design scheme.
