By the way, I'm aware that the "hidden" text on my Lock In post isn't hidden, though I hope it's unreadable. But I just spent 30 minutes trying to decipher the source code and get that background color, and could not. And then I went to one of those sites where you create a color and it gives you the hex code - and even though it looked like a match to me, when I plugged it into the post it was anything but.
So I gave up. Sorry. The colors defeated me.
