Door Window

What color of panels should i choose for my silver-painted sliding patio door and 70" wide window door?

My livingroom+dining room combined is very long and it has one sliding patio door and one window. The long side wall is silver color, side walls are dark grey. My kitchen is green and opens to the livingroom. Floor is oak wood color. I like modern style home. I don't know what color of panels track i should go for these windows. Would very appreciate for some advice from you. Thanks very much...!

1] drapes are usually the color of the walls, the upholstery, or a combo of both.
2] if the view is really good, I'd go with a pale gray or soft off-white [ blend cover with walls ].
3] if view not so great, pick a color in the room you want to emphasize more [ from upholstery, etc. ].
4] throw a bit of the LR-DR colors on the view outside [ patio furniture, plants ].
