Shanidev loves black color and hate other colors, know why ?

Shani Dev is one of the Navagrahas. Lord Shiva himself has entrusted Shani Dev as a judge in the Navagrahas. No one has been able to escape from Shani Dev's fierce wrath and his sharp vision. Talking about the form of Shani Dev, he has always been worshiped in black clothes and only black colored things are liked by Shani Dev.
