I get these all the time. People want to know what they are buying, if things will match. Sometimes, it's pretty hard to tell the exact color from a picture, even if you have good ones. I usually go through google images (I search "hot pink") and find the closest match to what I have in hand and send the image. People are usually very grateful.
But, on the other hand, she asked the same thing twice, so that's weird a bit..
