Pretty in Pink

Thank you for the reply. In my context it was a comparison between two computer viruses:

"VirusA makes VirusB look pretty in pink."

Hello,

Can someone explain the meaning of phrase "pretty in pink" and its origin. Context:

makes look pretty in pink.

Thank you.

It's a compliment paid to young, fair girls, "You look pretty in pink. That's your color." Meaning she looks pretty in a pink dress, sweater, etc. And then there's a movie by that name. That's all I know.
