Simply tap the square that doesnt match the rest. Seems easy enough?
ColorSquared is a simple game of spot the difference. With each level the difference in color becomes smaller and smaller. How far can you go before they look identical?
Are different colors easier to distinguish than others? If a blue becomes a lighter blue, is it easier to find than a green becoming a darker green? Part chance and part skill, this game will test your ability to quickly perceive colors. It may not be the most complex app, but its a great way to pass the time, or challenge your friends.
