So I was stumbling around the internet and I found this: 40 Minimalist Superhero Portrait Illustration Designs.
I think it is really amazing that with just a few shapes and colors we can convey. For the most part all of the superheros I could easily recognize, and I feel that if they were on their own (as apposed to a group of illustrations) the majority would be able to stand on their own.
At the bottom of the page there’s an infographic on comic book color palates which I found to be an interesting read (http://static.colourlovers.com/uploads/images/ComicColors_Infographic.png). It’s neat to be able to see a visual representation of the differences and similarities of the two major comic book industries (DC and Marvel) and to see how their use of colors vary. For example, DC comics have always seemed a lot more darkly colored to me than Marvel, and so it was nice to see in the chart (of which colors were used the most and their percentages) some confirmation.
