Are you talking about diluted acrylic paint? Both types of paint as they are have a huge difference in what brushes can easily hold them.

Yes, diluted acrylic paint. I didn't know that other variety also exists. @Joachim

@Aquarius_Girl Please keep in mind that my answer was written under the assumption that you meant "water color" instead of "water and acryllic paint". These types of brushes are ideal for very watery paints and inks. For more viscous paints there are other shapes of brushes that have different properties and are commonly used for different techniques. For regular acryllic paints it's almost always adviced to use synthetic brushes because the acryllics and other additives damage natural bristles.

@Elmy I did not know the difference. I thought water colours and liquid acrylic paints are similar.

@Aquarius_Girl Well, they are mostly similar in terms of how to work with them. Water colors can be dissolved again (and cleaned) after drying, but acryllics can leave permanent stains and harden the bristles of your brush. There are special "brush cleaners" that can dissolve dried acryllic paints, but those (and other) chemicals damage natural bristles.

@Elmy I will raise a separate thread for questions about acrylic paints.

How to choose a synthetic brush for water colors?

# How to choose a synthetic brush for water colors?

(Asked by: username_0 on 2021-05-18)

Well, synthetic brushes are considered horrible for their water holding capacity as compared to natural hair brushes.

Now, if I have to choose best out of the worst - how do I do it?

Do all synthetic brushes have horrible water holding capacity or there are some exceptions?  
What should I look for in labels or anything else before purchasing them?

I think it goes without saying that softer paints need softer bristles. In my personal experience, the best brush for water colors looks a lot like a calligraphy brush (just a bit smaller). You should look for **thick brush heads, long bristles and a pointy tip**.

Thick brush heads means that there are a lot of bristles in it. More bristles means more tiny spaces between them where water can be stored.

Long bristles can also store slightly more water than short ones. They also tend to move more fluidly and have a softer stroke. It's hard to explain, but I had better experiences with long bristled brushed for soft paints like water color.

A pointy tip means that the bristles in the center are even longer than at the perimeter. Those longer center bristles are the ones you want to actually paint with. The ones around the perimeter are mainly there to store water or ink and to keep the center bristles in shape.

Here you see that only a small number of bristles actually touch the paper and write. Yet traditional calligraphy brushes have these thick brush heads to retain ink and their shape.

The same can be applied to synthetic watercolor brushes. On the largest brush you can clearly see the shorter bristles surrounding the longer ones at the center.
