I love Solarized color-scheme and this addon applies it perfectly, even on dark pages.
I'm missing an URL white-list, because there are some pages where I would prefer the original colors, but right now there's no option to prevent it, nor to get back the original colors once the addon changed them.

It happen Solarized Light is one of my favorite color scheme.

Applying color to site seem a bit slow. Sometime the script timer warning kick in. Not that big deal for me.
