Plasma almost appears to be an FMJ frame, but it isn't. Instead, it resembles Metallic Sand, but with more of a "silver" hue. Oakley seems to have created this specific frame just for the Gold Iridium lens.
I have it on Mag Fours. Great color, looks awesome with Fire Iridium.
Hard to say what "Plasma" is when looking at the X-metals. The first Juliets had a plasma that was a matte-gold color (that had major issues with flaking and discoloration), which changed significantly by the 2nd gens. The Ice 2nd gen became a darker brushed silver, and the 2nd gen fires (the rarest of the plasmas) took on a brushed bronze look. After, all of the plasmas became a brighter brushed silver - which is still in use today. I would have to say that "Plasma" only applies to the first or Second (fire) generations of the Juliet line, since they have the gold-tint to them. The others should have just been called "silver", or something to that effect.
Have this on my Splice's. It works with the Gold lens, but not on much else.
Really nice color option for Half Jackets. I would prefer pearl but it does give the look of a Plasma Juliet. Plasma frames look good combined with the ice and gold iridium lenses.
Very good looking frame color. Almost looks like x-metal plasma.
