I got the above definition from Urban Dictionary. I am not sure I understand the usage of it.well color me surprised
A phrase used when you are surprised and impressed with an outcome, especially when you were sure nothing good was going to come of it. Similar to saying "Well I'll be damned" or "Well I'll be a monkey's uncle".
1. If it is a good outcome, can I say color me surprised?
For example, if someone gave me a pleasant gift, and is it okay for me to say, "wow, color me surprised"?
2. Does color refer to "I" was too surprise about the outcome, so I change the normal color of my face, i.e. turning pale, blush, etc.?
