Truth be known, even I'd thought this background was some shade of off-white or even white. It was many moons ago, that I popped a graphic into the text space and discovered the white graphic background didn't match the color of the text area. I poked around and found the html code for the background.
Loo and I have fussed about the colors of things on my blog, so that one day I brought a particular item to the computer and compared it with a posted photo. Winning is SO important, don'tcha know. Since I was looking at the real deal, with the photo also in my face, I could confirm that I was seeing true color on my monitor...even if it is a cheap little thing, not nearly as nice as Cousin Annie's planned purchase. *major snorting*
You are about to see -- or not see -- two color blocks in the center of this text box. Ya got white on the left and off-white on the right. They're sitting on this green background, and I deliberately didn't put borders around them, so you may have to hunt -- especially you, Cousin Annie, since you've been looking at chicken tails and bits of straw. There's no tellin' what you're going to see!

For cryin' in a bucket, is this a slow day, or what?
I'm all done with my color tutorial now.
Something tells me y'all won't be done with me.
Oh worra, worra, worra.

Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. ~Isaiah 1:18
