I can't be the only one frustrated at this

Title says it all, why do some text have to be so dark to the point where it's extremely hard to read? If the point is so that white theme readers could read it normally, what's the point of having any theme at all? Seriously. Of course I could go to white but I particularly like this theme I am in right now and it is such a bummer for that black text to be unreadable.
