This image shows and actual sunset on Earth compared to artistic representations of the best candidates for habitable worlds discovered so far.
It corrects for size, colour, brightness of the star and approximate distance from the star. Kepler-22 looks so similar to Earth because it’s star is very much like our Sun. The suns of Gliese 667Cc and 581d look so red because they are both red dwarfs. The sky of Gliese 581d is dark because it is much further away from its star compared to the others. HD 85512b is the brightest of all .

Mohamed Babu from India, captured these amazing pictures last year after his wife noticed that ants turned white when they drank milk.
He dissolved sugar in food colouring solutions of red, green, blue and yellow and then placed them in his garden to attract ants. Some of them even moved between the different solutions, resulting in psychedelic colour combinations.
