My friend and fellow artist, Chris Legaspi, has just released a new Gumroads course on color and painting:
The Laws of Color Vol.1

Chris is a painter and instructor at Gnomon whose work was recently featured in Imagine FX magazine. He is providing a fully structured course with professional level production quality. If you're looking to take the fear, guesswork, and mystery out of painting, then this is the perfect course for you. Check out the above link for more details.
