We are planning to put up 4 different paint samples on a wall. When I wash the paintbrush after each sample, how dry does the paintbrush need to be before I move on to painting the next sample? Does it need to be 100% dry? If so, can i accelerate the drying with a hair dryer or other method?

I flick a wet brush into a towel so any liquid goes, then rub the brush with the towel while bending the bristles. Also I like a damp brush, so I wet it before starting to paint.
A mini roller is my preferred tool for sample testing. A brush messes up the texture.

Thanks! Just put up all four samples with washing off and drying off the brush on a towel in between each. Didn’t want to make another trip to the store tonight to buy anything, so glad that a damp brush was sufficient

Buy disposable brushes at HD or Lowe’s. Put on multiple coats to ensure coverage. Wrap in plastic between coats

If it's not dripping wet, you're fine. Wash it out, hit it with a paper towel, and you're fine.

It can be damp, especially for just doing samples. You want it dry when painting as dampness in it while using it for a while will start drawing paint up to the ferrule, making it hard to get clean. The easiest way to dry it is to spin it by rolling the handle back and forth quickly between your hands. They also make a spinner you can buy that does the same thing.

If it's dry when painting, the paint will slowly get sucked up the ferrule. You're supposed to wet the brush with water before painting so the water is inside the ferrule already to keep paint from going up there instead.
The spinner is great for rollers, horrible on brushes, especially anything of quality, it is too hard on the bristles. The hand rolling technique is sufficient.

Sorry but I disagree about the water from personal experience painting with a dry brush versus one after I washed it. Especially on ceilings, you get diluted paint running out of the ferrule and it makes a mess. When it's wet, it thins the paint, lowering the viscosity. I can use a dry brush all day and not get paint to the ferrule. Use a wet one for an hour or two, and it does. And it's worse with epoxies and solvent based paints. You can see for yourself with a little experiment. Take two similar brushes and wet one of them. Put a 1/2" of paint in a cut pot. Set the brushes in the cut pot and walk away for an hour. When you come back, you'll see the wet bristles have paint bleeding up the bristles well above the line it was submerged to, while the dry one won't.
Looking around on Google, it's a mix of some saying you should, and others saying don't do it. It depends on which source you look at. Neither Sherwin Williams nor Purdy recommend it, but I see people on quora and other places saying you should. So I'm gonna go with the guys who make the brushes instead of of randoms on the internet. Nothing against you if it works for you, but I just imagine a person who's not a pro painter making more of a mess with a wet brush. And all the sources that do recommend it say it is too help with cleanup. Other sources say it's bad because it dilutes the paint. So I wouldn't recommend to the average home owner.

Damp is fine. For future use, get a brush & roller spinner. They're like $10 at the local big box stores. They spin your brush real fast and it ends up damn near dry.
