I think as long as you keep the exterior color consistent, it's fine. The window over the foyer isn't going to match unless you're going to get up and down a ladder every night to raise or lower a shade, which you're not. In that case, I'd just use a fully retractable window cover, like the roller shade or duettes so that, at least, during the day when you're most likely to see them, the windows will be largely clear.

If you do choose to put a valance over the bedroom windows to hide the shades, then you may wish to put one of the same shape over the foyer window as well...they don't need to match color on the interior, but make sure the exterior lining is the same.

You can put a shade that has a control from the floor (not cheap) but doable.
