The library column names are too light

Can we get more contrast with the column names please?  Medium gray on light gray doesn't make for very readable text.  It's quite readable when the mouse is pointing at one, since it gets darker to highlight it, but I'm not seeing the need to make the other column names so light. I wish they were all the same as the one with the cursor over it.  Perhaps some other way to highlight the clickable nature could be used.
