You could do room darkening curtain panels. Pick a color close to the wall color and have them completely open during the day so they blend with the wall.

You could also do pull down blinds with a narrow valance. Again, close to the wall color so the valance would blend during the day.

Plantation sliders! I have 4 sets in my Florida home.

Our office

deegw....thanks. So far I have side panels in both the approx. wall color and a coordinating color to try. We'll see. Just me, but I'm not sold on a pull down shade on a sliding door. Just seems a bit physically cumbersome....but I appreciate the photo and the idea.

eld6161.........thanks. I too am in Florida. My second shutter vendor was here yesterday to measure and price, etc. The first told me I would find the slider "cumbersome", the second disagreed....and offered a reg. slider or a bi-fold slider. Did you have that option and did you use a bi-fold design anywhere? I do see where it would allow in more light, balance the visual appearance of the door when both open, but I hadn't even been expecting that option and I am typically NOT a bi-fold fan.....thx for any additional info you can share.
