The Warm and Cool colors work because they are used to convey a certain message and emotion. Warm colors can convey messages of happiness and anger, while cool colors can be cold and comforting. http://www.truth-is-beauty.com/please-explain-warm-and-cool.html
Watercolour cheat sheet - discoveries in mixing skin-tones. I try to find paints that make it faster/easier to mix skin colours. The one I have most success with is “violet gray”, then “permanent magenta” for darker and wider ranges, and “purple lake”. Mix these (sparingly) with raw sienna. The darker the purple the less you’ll need to add to your yellow (yellow ochre works as well). For a lighter, paler, redder skin tone, raw sienna + brown madder is what I prefer. #watercolors #techniques
I tend to work in a variety of different ways- Sometimes I start by drawing or doodling in pen. I then go back into my drawings and fill things in with color- kind of like a coloring book. This is where the magic happens! Color brings everything to life. In my opinion this process lends itself to doodles and drawing things that have more details.
