I figured I'd do this for fun. Here I have a few Lightsaber shots from a few VHS copies and 2006 DVD aka GOUT of ANH. First is a shot I always get a kick out of when I watch the pre-1995 NTSC Pan and Scan VHS versions of ANH. It's the shot of Ben in the cantina holding up his lightsaber. As you can see its extremely washed out, hardly a hint of blue. If you squint you may be able to detect a hint of blue but not much.

Next is Luke's saber in Ben's hut. First shot is from the 1992 VHS which print is virtually if not completely identical to the VHS prints before it. Here his saber looks blue with a slight hint of green. Second is the 1992 Letterboxed VHS which as you can see although its a bit bright looks more greenish compared to the P&S version. Third is the 1995 Pan and Scan VHS which uses the same print used for the 1993 and 1995 Widescreen Laserdisc and GOUT. Here much like the '92 VHS it is blue with a hint of green, giving almost a teal look to it. Last is GOUT which as you can see the green tint is gone for the most part.

Last are three shots of Obi-Wan during his duel with Vader. First is from the '92 VHS, second from '95 VHS, third from GOUT. Mostly here I wanted to show how the blades look somewhat thinner in the pre-95 releases compared to the latter versions. As you can see below Ben's saber looks a bit thinner in the first image compared to the last two. You can even spot this in the above shots I posted of Luke.
