Gido, the bottle you're referring to is NOT a different scent from Comme des Garcons. CdG does limited edition bottles every year and they have one of their scents, rebottled. That bottle you saw was just one of the normal CdG scents, in a red beaded bottle.
Looking back over the limited edition releases, I think that beaded magenta was actually the original Comme des Garcons EdP.
The green bottle you mention, sounds like it is Comme des Garcons Cologne. Which is a 'lighter' interpretation of the CdG scent - some prefer this for Summer.
