That surprises me given that, to the best of my knowledge, film has always been most sensitive to blue. Then again, throw on an orange filter and you're killing two birds with one stone with the blue lipstick - dark lips and glowing white skin. It would obviate the need for a blue filter (thus lessening the need to cake on the make up) and would avoid zombie white eyes for those of us with blue eyes.
Okay, that works for me
Actually, now that I think about it, it doesn't make sense. Maybe if they'd used red lipstick on ortho film, the lips would have appeared black, which is why they used blue lipstick to get a slight shade of grey to the lips. That makes more sense...
An awful lot of electrons were terribly inconvenienced in the making of this post.
