What fixed frame projection screen size will go with Optoma HD700x?
The HD700X is native 16:9 aspect ratio. But it doesn't really matter since you can use any screen aspect you want and the proper screen size is determined by viewing distance. For example, it will fill a 100" screen at 11.2 - 12.4 ft (see link). That said, what size screen you should have for a certain viewing distance is also a consideration. Bigger isn't necessarily better. See the second link for discussion and a calculator.
So ... you need to decide what aspect ratio screen first and then what distance you will use, and that will determine the size screen.
The choice of aspect ratio is usually based on what type of images you will watch most. Since movies are most frequently 1.33:1, 1.78:1 (i.e. 16:9), 1.85:1 or 2.35:1 (with a few more just to keep things interesting), and HDTV is usually 16:9 / 1.78:1 there is only one aspect ratio that completely fills the screen ... all others will have bars on top/bottom or sides. For most people who watch HDTV and movies 16:9 screens are a good choice.
I don't know your intended room or viewing habits ... but you won't go far wrong with a 90-100" 16:9 fixed screen.
That said, given the relatively narrow zoom range on the HD700x you would be advised to consider the screen size/throw distance relationship carefully before deciding on the screen. If you ceiling mount the projector you will have to be fairly precise in positioning. personally, I prefer to mount projectors at the back of the room on an adjustable shelf (and then you can move them as required to hit the screen correctly. But with this type of projector you have to get the relative position of the screen and projector right because there isn't much leeway.
Also note that the screen height should be such that you eye when sitting down should be about 1/3 the way up the screen. In other words, if your seating puts your eye at 38" from the floor, the bottom of a 100" 16:9 screen (87"x49") should be about 2 feet off the floor.
As to dark pink, it isn't clear if you want to project direct on the wall (vs hang a fixed screen on a pink wall), but if so it's not a good choice to project on other than white or light, neutral grey. Wall colour doesn't matter if you use a fixed screen over it.
Hope that helps.
