I love having a blanket nearby when I am watching TV or reading a book. Purchased two blankets to use while lounging in our living room. They are very soft but not warm.So I decided to buy a new one. My friend recommended me HS.
pink color blanket are fit your grey modular sofa.
i think cream color could be fit for your cool grey modular sofa. cream color look always good to see.
The dark grey could look good but it is not a cool grey like your sofa. So be aware that the sofa will look more blue in comparison to the throw. Otherwise, you could go with the ivory colour but it would have to be laundered more often.
