The green are being replaced by the newer reds. The three differences (apart from the colour) are :
1-all new lenses (except, I believe, the 40) have rounded aperture blades (good for bokeh, bad for starburst effect).
2-All new lenses have the newer HD coating. The previous coating was already fantastic, this one should be better, though from my personal tests with the 21 it's quite hard to see any difference.
3-The newer lenses ditched the "Pentax" lettering, replacing it by a more business-like focal length/aperture engraving. I don't like it

On my version there is a Pentax logo indeed. But since it's a scre-on cap, I left it in the lens box and bought a 2$ snap-on replacement.
