Colour me shocked

What does it mean? How do you use it?
Thanks

There was a phrase "fad" a few years ago, "Color me..." Here's a explanation from the archives:

"It was being used as long ago as 1969. From the song Calgary written by Ian and Sylvia of Great Speckled Bird;
Color that jet plane going,
Color me gone.

Presumably it comes from the instructions in a children's colouring book and means to give an appropriate colour or description to something or someone...
