If you have different visor shades, post them here for others to see. I just ordered the classic Fibremetal "Dark Green" visor that TK409 used (around $5) AND a Fibremetal "Shade 5.0" visor (around $18) from RJSafety.com. The "Dark Green" is a LOT greener and more transparent than the Shade 5.0. I was not sure whether the "Dark Green" was closer to Shade 5 or Shade 3, so I bought it to find out. I took photos of each with the flash on.

The "Dark Green" is obviously green, even with a dark surface behind it. There has to be nearly zero light transmission behind it for it to appear black. Even then, when hit with a direct flash, it's transparent and appears green. When pressed against your face, the transparency of that is better than the Shade 5.0 - acting more like a tinted toy lens and less like sunglasses. This appears to be more like a "Shade 3.0".
The Shade 5.0 appears black unless there is light on the other side of it, in which case it appears a dark green. It has a darker tint, kind of like some dark sunglasses, when pressed against your face.
My recommendation: splurge on the extra $$ if you have to and get the Shade 5.0.
