Could you tell what the difference between Watercolor, Gouache and Poster Color is? If your answer is no, don’t worry you’re not alone and I’m here to tell you!

Let’s start with what they have in common!

All you need to start painting with those colors is water, a brush, paper and of course the paint! Watercolor, Gouache and Poster Color are water-soluble which also means that they can be reactivated with water so that you can lift off the paint with a tissue paper. (When it comes to watercolors the result of lifting off the reactivated paint depends on the paint and the paper!)

You can use watercolor paper for the three of them but for Gouache and Poster Color you can use any other thicker paper as well!

Which leads us to the differences!

Watercolors are made of finely ground pigments, whereas Gouache is made of larger pigments and Poster Colors pigments are even larger! That’s why Watercolors are more transparent and Poster Colors are more opaque and Gouache is somewhere in the middle. The opacity grows with the pigments and its additives!

You can paint in multiple layers to create depth when you’re using Watercolors and you should leave out white spaces cause you can’t apply white watercolor on top. That’s why you need to plan out your painting before and use masking fluid or tape to keep areas white.

Gouache and Poster Colors are, as I mentioned above, more opaque which means you can paint from light to dark and from dark to light and even paint on colored paper. You can layer gouache and Poster Colors or thin down the paint with water. (But you need to be careful to not reactivate the paint underneath and create muddy colors!)

In the video I’ll go more into depth about the differences and explain to you which paint is good for which purpose and what you should choose!
