So you're running two threads on this space? I think you'll be happier with the responses if you stick to one thread for the entire makeover, as it is all inter-dependent - foyer - living - dining. Now that I know that the living dining are together I'd suggest you use measurements from the blocked space above the windows to determine stripe width in the dining space if you go with the wide horizontal stripes I suggested. The pattern is already set for you if you take the measurements. You could also make the stripes the width of your lower window section, or half of it, but use the horizontal lines already in your space to determine the other stripes you may add.

There is a specialty lighting store near me that I am going to soon with photos to work on lighting at my house. I will show them your photo and see if they have an idea. Probably won't be till Fri or Sat but will get back to you.

I'd suggest you have a look through the photos section on Houzz - or there's quite a few good articles on how to decorate :) maybe both you & your wife could save pictures to an ideabook with a few words on what it is you like about each one, and it'll give you more of an idea of what type of things you like? I think colour-wise, turquoise and peach can go together really well - maybe a warm cream colour on the walls & pops of turquoise and peach in the form of throw cushions etc.? Again, just searching on Houzz can give you some great ideas - just literally searching 'turquoise and peach' brings up quite a lot of pictures :) to get you started I've just picked out a few which I personally think work well :)

Romney, First thing is that requirement of light is measured in lumens. Secondly , you will have to look at the room requirements , colors on the wall, furniture, flooring etc. Even the temperature (i.e. warm or cool) of the lights is very important. Depending on your requirements an appropriate suggestion can be made. Please share some room pics along with query. Thanks, Nitin Cornerstone Designs, Bangalore.
