Because the chocolate buffalo plaid appears to coordinate with your sofa, what about coordinating draperies in the other room with the chairs, but in a lighter shade (given that walls are painted blue and room may appear dark on overcast days)?

Alternatively, select a white/cream from the buffalo plaid.

In either care, raise the rods to a distance halfway between the upper window framing and the ceiling. IMO, I'd also suggest widening the width of the curtains by at least 6". Your rod supports appear to be too close to the window framing.
