Is it just me or can anyone else see this? To the right hand side of the page, where the UK net guide is, behind all the black links on the grey part, I can see a light green kind of shading. Is this just me going mad or is it really there?
It's not just you. When I look at it I see one of those 'magic eye' things. It's a picture of 6 dolphins jumping out of the ocean. So don't worry, you're not insane milly.
Red and yellow are commonly used on tests to determine colorblindness. The human eye sometimes is a little tricky. People may be looking at the same color, but their brains may compute if differently. =) I used to pre-test patients before their eye exams. Sometimes red looks green to people, that's why stop lights are always in the same sequence.
