candy corn strangeness

i bought some candy corn on impulse yesterday and ate some/a lot. when i was flossing and brushing last night, i discovered that my teeth and tongue had bright, almost fluorescent, pink all over them. i'm assuming it's from the candy corn since that was the only artificial thing i ate yesterday (i think,) but that's weird isn't it? should they stain, shouldn't it be orange? i mean, i bought the classic candy corn, yellow/orange/white... how strange. i'm going to eat some more tonight to see if this strange phenomenon is consistently linked to candy corn consumption. and just as a side note, everytime i eat candy corn i think about making a giant candy corn on the cob by sticking them together with frosting. but due to my innate laziness, i've not accomplished that yet. it's been on my to-do list forever.
