Color issues on skins

[snipe]

Default skin (and probably others)

That active text should probably be white so it's more legible.

Column selector

I know this was a compromise we made, but I think we have to make the icon color dark if it's going to be on the grey background - it's too hard to see otherwise.

Help popups are not readable (white on light grey text)

Also the hover turns blue once you click on the help icon and move your mouse away.
