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.

I don't know where these pictures originally came from
so I just attach one of the links
