I'm a beginner, can someone teach me how to use the wet blending mode?

@Vio,
according to the example you posted, it ssems you like the mixing and the impasto style shown there.
Maybe the Memileo brush bundle is interesting for you.

Memileo Impasto Brushes

[banner_01] Thick paint/impasto style RGBA brushes. Here are some brushes that tries to imitate some thick paint features. The light direction is baked into the animated brush tips to make it appear as if the light shines from a fixed angle (roughly). After about a year of experimenting and tweaking these off and on, I think they are done. Big thanks to everyone who gave feedback and for the wonderful paintings posted in the WIP thread. And thanks to the excellent Krita developers…
