No, it doesn't affect the snippet getting copied to the clipboard, it just looks a little strange when you're scrolling through the list of snippets and most are at the top of the window, left justified. Then you come across a 6 character snippet of valid hex characters and it shows the color (which can be an awful color 🙂), and the associated text is centered at the bottom of the window.
It seems like there should be a more specific way to indicate an RGB color string, so that standard strings are not processed as colors.
