The magic number is...?
How can you find out if there’s a colour in the spectrum that you can’t see? Well, this rather pretty (and slightly tongue-in-cheek) Colour Blind Clock
The printed face of this toughened glass
wall clock features numbers three
, hidden amongst the dappled dots. Their only difference from the dots around them is their colour. If you can see them – hurrah! You’re not colour blind. If you can’t see them – congratulations! You can count yourself alongside Mark Twain, Jack Nicklaus, Bob Dole and actor/warbler “Meatloaf”.
