I think I'll ramble on a bit more about lenses, only because it is still irking me. These just don't look right, I mean MY glasses don't make anything look darker/lighter than they should.
I actually like the text, adds a bit of color and tone.
Mine does! They have a very subtle smokey brown tint that darkens in UV light.
Mine do too! D:<
Who sleeps shall awake, greeting the shadows from the sun
Who sleeps shall awake, looking through the window of our lives
Waiting for the moment to arrive...
Show us the silence in the rise,
So that we may someday understand...
The whole Llewellyn's-skin-looking-lighter-behind-his-glasses thing could be accounted for IRL by mild glare off the lenses perhaps. Derrick Fish, for what it's worth, actually lightens the outlines behind the lenses of glasses on characters that have them, which makes for an interesting effect.
