Here's a link that shows pics (first) of hemmies, under the hemmie pics it shows pics of perianal crohns skin tags (aka: elephant ears)...which are related to CD only.
What you're describing sounds more like it's hemmies because of the colour (perianal crohn's skin tags are basically flesh coloured)
