Had some more practice with gouache again and results have started to become more satisfying. My biggest problem has been to mix colors while still maintaining the values. I would quite often paint over areas that should be brighter. On the cheap sketch-paper I’m using for practice doing washes is not really an option so tinting can become difficult. I discovered though, since gouache is water-soluble I could always thin out the already applied paint by adding water, spreading it out to make gradations. So what I’m doing now is to apply paint where I want the darkest to be then spread it out with water thus make shading happen. So far I’ve only gone monochrome for this approach, but once I have the values down tinting with other colors may perhaps become easier. I’ll have to try out and see.
