Just for the Hell of it I took the two lightsabers from the two different caps and sampled a series of several random pixel shades of the saber itself starting from the outside glow moving progressively closer to the core and plugged those values into a series of cascading tiles with the upper square representing the furthest from the core and the lowest representing the nearest to the core. It sort of makes an easier visual comparison of the stark difference between the two hues.
That's what I mean by perhaps a touch too much lean towards green in the first cap.
