What window exactly?

Choose a solid color from the drapes that you want to highlight. Or use the cream background color with a trim of blue or green.

Thx for the suggestion of doing panels instead of valance. The window with plantation shutters also I think would need the same treatment - yes? Put those on to block view but do not want to block view out of the triple window as it provides needed natural light.

Can you still get the IKAT drapes? Use those for the triple and leave the shuttered window alone and closed.
