If you’re looking for an out-of-the-box color inspiration, check out the color palettes curated at ColorLisa.com.
A project by artist and designer Ryan McGuire, this website curates color palettes based on masterpieces of the world’s greatest artists.
Next time you are looking for colors for your book cover, try experimenting with some of these color combinations. It can be a great way to incorporate some of the old masters into a new work. How cool would it be to say, this book cover is based on Degas? Or Escher? Gauguin?
This gives design a whole new (hidden-meaning-awesomeness) kind of feeling.
