I do think you will be sorry if you don't match them .. and I don't think the other space will benefit from the higher contrast. Warm gray will work well as a neutral there.

Wow! Two completely different points of view. I agreed with both as I was reading them, and I see both points. Thanks for taking the time to weigh in.

I think in this scenario, I would use the same color....the color in the family room will still be a nice contrast in your kitchen!

Thanks! Still split opinions. Keep them coming.

The shades don't need to be the same, even if you see them at the same time, as long as the styles are similar. I would match the color to the paint color, or trim color, in each room. I don't think a contrast will look nice in the kitchen. The point of roller shades, and solar shades, is to have them disappear.

I think (and it is probably old fashioned) that what is seen from the outside should match. I did Hunter Douglas Vignettes in white on white in my DR and a cream color in LR but the back sides are both white. That said with roller shades both sides are the same so I wouldn't do a light color in one room and a dark color in another when the windows are on same side of house.

I often notice the windows in a home, and I think that the window treatments can make or break the home's appeal. So, IMO, it does not matter so much if they all match, but it does matter if they make the windows attractive. Pretty curtains or cafe shutters are my favorite.

The current trends often do not look good from outside. Far too often the window treatments look like there are sheets at the window or that they are covered with paper. Shades in a variety of colors is my least favorite.

Your room should 'speak' to each other when visible. You have a unique situation with the dividing wall. You also have an outdoor seating area to consider.

I would do the same window treatment style. The color should be light but don't feel they need to be the same color just as the wall color does not need to be the same.

Thank you everyone for sharing your opinions. Calidesign, what you said really spoke to me. Prairie Shades, glad to hear your point on keeping the same treatment style. Others have suggested this too. Since I am not getting new window treatments in the family room, I will keep the same treatment style with the kitchen nook. When we moved in to this house, every room had a different window treatment (most often about three treatments per window!). It felt cluttered. I like minimal design. Therefore, I think I will keep the color visually minimal as well. Thank you all so much for your help tonight!
