I wonder if this is a test, or what. I have on occasion gotten pink, but normally it's just the normal green, pink or blue pastel. Never seen bright yellow before. And also, it was even brighter yellow than what the screen shot shows. It darkened the yellow when I converted it into a JPEG.
I kind of liked the color, definitely more visible.
I really like it. It sure shows up better than the weak blue. I used to sell Yellow Pages advertising many eons ago and have always liked the bright yellow for attention. These are ads afterall. I use yellow highlighting behind important features throughout our websites to give them more impact. We think it works very well.
