Get creative. You can create your dream closet in otherwise unusable rooms. An awkward attic space with slanted ceilings would be used for storage of seasonal decorations, winter coats, and old board games. This wise homeowner created a storage haven with custom built-ins that maximize the atypical ceiling heights. A skylight provides natural light and the white cabinets with white painted walls and white ottoman upholstery allow for a clean canvas against which to build outfits.
Good luck!
A roman shade tpe would work. You could put two up- side by side, then you can either open both or just one side at a time. See if plastic shoe boxes would fit on your shelves for shoes, if shelves are adjustable, hopefully you can stack two on a shelf. If you put all colors together, it will look more organized. Put all hangers with the hook facing you, when you wear the item, turn it around. You will know what you wear (most of us have favorites and wear 20% of our clothes 80% of the time) after a season or year, get rid of the items you dont wear. This is more than you asked..as a professional organizer thought you may like some additional comments.
A nice curtain on grommets would be a great solution. You can add a curtain tie back hook on one side if you don't want to slide it open and closed all the time. (Don't throw the sliding doors away. If you own and want to sell, buyers will want the doors back on the closet, and if you rent, your landlord will ding your deposit if you don't put them back.)
The shelves in your closet appear to waste a lot of space. You can buy pull out fronted, stackable plastic bins that would hold sweaters, shoes or purses and make these shelves more organized. You also might try an over-the-door wire shoe rack to hang on the back of your bedroom door. There are some out there that hold 18-21 pair of shoes. Also, it appears that the hangers on your closet's bottom shelf are the bulky, wooden kind. You should trade these out for the thinnest non-slip hangers you can (Huggable Hangers are great) and hang pants on tiered hangers so they take up the least amount of space.
the ikea chest/shelving components shown in this section might also be a consideration to provide

Also, what is a good color for a closet--does it have to match the bedroom color?

a breeze to work in a well thought out closet. But the more space you have , the more you tend to clutter up your space. Therese / Clutered Solutions.
