Convert RGB/HEX etc to paint formula

I have used a sprayer to paint my house before we moved in. While I can't qualify how much more paint I used, it did feel like I used more compared to rolling, but I think part of that is because it goes so quick and I may have been painting over the same areas more than I would have with a roller.

One thing to note though, when I sprayed my home, there was nothing in it. No flooring, window treatments, etc. Spraying, no matter how careful, will leave some atomized paint in the air, which will eventually hit the floor or whatever else you don't want to have paint on it. Be prepared to mask, tape, and tarp everything you don't want painted that can't be removed from the room. You will want a mask and a respirator of some kind (you probably don't need anything fancy). The mask I used had a roll of film built in it so that I could get a "clean view" when too much paint got on it. That was especially handy when doing the ceilings.

Personally, now that I have moved in, I would roll instead of spray.

Good question Nick. I manage several rental units and have dealt with the same situations. Originally, flat paints were used in most of the rentals and almost every couple of years they needed repainting especially if kids were in the unit. Flat paint is hard to wash and very susceptible to marring and finger prints etc. The newer flat enamels are better, but not great. I changed over to a harder eggshell finish. Depending on the time a tenant is there, the eggshell really outlasted flat, usually good for 3 to 5 years unless damaged. Satin enamel works great for ceilings, hides marginal imperfections and very easy to clean between tenants. I have also found that since looks is more important than durability, I have used a lot of PVA grade wall paints from Ben Mor. At contractor price, it can be almost half as expensive than premium grade paints, covers well, lasts for several years. I have given up on expecting paints to be show ready after a few years in a rental. Cleaning and touching up walls takes almost as long as painting so a new quick same color wall paint job between tenants freshens up the place and smells new when showing the apartment. I tend to use just a couple of colors for most everything, so I buy 5 gal cans for economy, batch small leftovers and treat older paints with Flotrol. Be sure to keep the color formula in a notebook (ask for an extra sticker) so you can buy a good match later. Changing colors always requires two coats, but one coat of same color is normally fine. You can use your leftovers with new paint if you strain it through a mesh colander and batch it with your new paint, thus slight color changes disappear.
