Basement finishing input

Ok guys and gals. I'm planning on redoing my basement. Currently poured concrete walls concrete slab. I trying to stay budget friendly on this project so I'm spraying ceiling flat black and going the industrial loft look with open joists. Framing walls and drywall however due to a drain pipe running 3/4 of the basement I'm required to frame inside of this so there will be approx 4 inches from frame to concrete wall. My question is at the top of the framing at ceiling joist I will be able to see the bat insulation at the rim joist although set back 4 inches or so it will still show additionally for interior walls I will be able to see above them inside joists into a utility room. Is there any easy way to fill in this area above from inside of joist. The only thing I came up with is either rigid board or drywall. I'm sure it's tough to picture what I'm talking about. Best way to explain is framing an interior wall perpendicular or across the joist this will create a cavity in each joist Bay which I think will look unfinished. Any ideas on how to make this look acceptable. Thanks for your input.

Do the same thing they do in commercial buildings frame all the way to the floor above and finish it with drywall or wood
If your insulation has paper backing, just spray it black along with your open joists. No reason you can't paint the paper backing and hide it along with the ceiling.
With the black paint you may want to consider budgeting for at least a dozen LED light bulbs.
Planning on plenty if led bulbs in here. Yes it is paper backed indulation. I was thinking of just painting it as you said. So I guess I can go that route on exterior walls to allow access to mechanicals. And frame to ceiling on the few interior walls to give a finished look.
Also planning on crown all around to give top edge of drywall a finished look.
I think you should reconsider drywalling its a huge fire issue especially after you spray it with a combustible material that likely has a very high surface burn rate. Also you were probably issued a provisional certificate of occupancy stating you need to pull a permit and get the basement inspected. If you cant afford it now it would be wise to make it a priority to get your ceilings drywalled.

Another hazard is rapid fire development and spread. Many basements have no walls and doors. Many basements in private dwellings and commercial buildings alike are wide-open areas with large amounts of flammable stock, furniture and other debris. Once a fire takes hold, it can rapidly spread across the ceiling in seconds and trap or threaten firefighters operating down there.
Why black? Unless it's for a punk band, it is a poor choice for living quarters. White reflects light and gives a sense of open space. You will want general ambient light and that usually means larger fixtures.
Primary reason for black is bc i don't want to reflect light as half this area will be a theatre. Second is black creates a visual effect of no ceiling and since it is only 8 ft at highest not including duct work I didn't want it small I know opposite of what you said but through research and seeing it before with black the eyes don't draw to the ceiling where white they would. Additionally I am keeping with the loft industrial look woods creete metals. Broken up by area rugs. Lastly all the mechanicals will get sprayed so it will help them blend in more. Hope that makes sense. I can provide a picture of what I'm envisioning if that would help
Not my photo. But this will be close to my scheme. I'm going with light grey acid stained concrete on floor. Yes I realize cold and hard but not permanent and can change in future if I don't like. Plus probably most cost effective at this point.

I do a lot of the black basement ceilings. It's quite the rage now. Relatively easy, cheap, and black hides EVERYTHING, including wiring, plumbing, and ugly looking joists.
Just be sure to run it by your HO Insurance carrier, in case of a future claim (hopefully never); pipes/ducts exposed;

2x10+ wood floor joists can be left exposed;

Wood floor joists burn in 8-12 minutes, double that with 1/2" drywall ceiling... check local code requirements for "basement" finishing, may require a "ceiling" (drywall) per local amendments.
