I think the original poster is referring to leading ( or in web-speak line-height). It took me a bit to figure out what he meant.
the answer is not really.
It has to do more with CONTRAST and what in print is called "gray space".
So it gets complicated.
If you have low contrast headlines, you may not want to overpower them by having tight leading on your body copy. Of course the reverse also holds true, low contrast body copy with really high leading.. can lose the eye. The key is to find a BALANCE that reflect hierarchy. It's not as simple as dark = more.
ON a tangent, SMALL TEXT , can benefit from larger leading, but not too large. so if you must have 9px text please dont set a 10px line-height, it's bound to give the users headaches. Yet you could get away with 26px text with 27px line-height.
Another thing to consider is the font itself. I tend to give tighter leading to san-serif type than i do to serif type (on the web, the reverse is true in print)
for high to medium contrast fonts, a good rule of thumb for line-height is 1.4-1.65.
