Thank you for responding, but are you serious (no offense) ? (You do not have to answer that :D , but this pattern of response/lack of action still confuses/saddens/et cetera me since I been on WordPress.com & this has not changed sadly over the years, because I think that WordPress.com has a lot of potential & is not that bad except for things like this & lost potential)
I know about the Custom Design (I am not new & I follow the WordPress.com Blog/News), I know there are other themes (trust me I have tried many over the years & I look at each new theme when they are introduced), but why should someone have to pay and/or try another theme because of an obvious visual/color/brightness flaw made on the new default free WordPress.com theme when the WordPress Team who made it should have fixed/noticed this flaw long ago and/or could easily fix this simple flaw now? (Why would someone even want to buy something from someone who would make & not notice or fix simple flaws even when brought to their attention about users/a user?)
It is not that serious (thank goodness! or this situation would be even more awkward/strange/confusing/sad/et cetera than it already is) but a simple flaw like this should have been noticed and fixed long ago, and I just think that your response is an odd way to deal/not deal with a simple flaw on the default free WordPress.com theme; I would think someone pointing out an obvious flaw would be thanked & the simple flaw fixed normally.
I can understand if I was asking for someone unnecessary, but this is an obvious flaw where the text is almost unreadable/is unreadable (I thought that Twenty Twelve & most WordPress.com made themes were supposed to work toward being more readable?) & would be simple to fix I would think; and this effects/affects many people since this is on the default free WordPress.com theme & involves one of the WordPress.com widgets.
Anyway enough of my jibber jabber (from previous experience I doubt that it will help anyway), I do want to thank you for at least responding, that is better than nothing. :D
