What are gold standard, silver standard and bronze standard?
These terms refer to the level of detail in the coloring. I might not have this quite right, but I beleive Bronze standard would be similar to the flat colors used to color comics in the ’60s. Silver standard is a rendering style more reminiscent of animation art, with mostly flat colors highlighted with usually sharp tones, highlights, and shadows. Gold standard is the highly-rendered style we see in most modern comics, with feathered tones, highlights and shadows attempting to model both the shapes of objects and the lighting of the scene.
