This is the 1965 colour version. The colours are a bit saturated at this point.
This is a 1979 Eureka Vacuum Cleaner advert. The colours are brighter but still retain a faded drawn like quality.
This is from a Cadbury's Caramel advert from the late eighties/early nineties. Full blown, vivid colours, ink and paint.
This is from the Legend of Zelda: Wind Waker. When Sony Boy turns CGI, we thought a cel-shaded look was the way to go. We toyed with the idea of doing full-blown Pixar like effects, but we realised it would be impossible for use to do that. Rather than having a poor Pixar facsimile, we decided to do decent cel shading.
