3 things you need to understand before using gouache 🎨
1. Gouache is water-based and reactivates with water.
Unlike acrylic, gouache can be reactivated even after it dries. This affects how you layer, blend and work over previous paint.
2. Know what you can mix it with.
Gouache can be used alongside some mediums but not with every. You need to know what you can mix it with to create and explore different textures and usages of the paint without losing its characteristics.
3. Water changes the character of the paint.
Add more water and gouache becomes more transparent, closer to a watercolour wash. Use less water and it becomes more opaque and solid.
Understanding the medium is just as important as learning how to paint with it.
