I sometimes laugh (or snort) at figures of speech (like "don't go overboard with that new idea") because I have a vivid and comic mental picture (e.g. of someone waving their arms wildly as they tip over and fall into the water - literally "going overboard"). I understand the figure of speech; I just can't help visualising the literal meaning, and sometimes I laugh at the absurdity of the picture, while other people are totally serious, because they don't think about the literal meaning.
Maybe you were just taken up with the vivid literal image of someone turning white.
Sometimes I'll make stupid jokes about the literal meaning. Someone says "Can I see that?" I'll start snickering and then I'll say, "I don't know, if you can't then you should go to the eye doctor." No one else seems to find this funny, though.
