The rare property of pumpkin seed oil - dichromatism



(Warning: almost dirty word at 1:35)

Is pumpkin seed oil something that any of you have around your house?

I think we have vegetable oil, olive oil, peanut oil, baby oil, motor oil, and safflower oil. I'm pretty sure we don't have pumpkin seed oil.

In this video, Steve Mould breaks down how we see color (three cone cells in your eyes) and how translucent liquids show the colors that they show...especially how pumpkin seed oil shows two totally different colors depending on how deep the puddle of liquid is.

I wonder if there are any artistic uses for pumpkin seed oil.

(By the by, you can see a more accurate version of the pumpkin seed oil spectrum on wikipedia.)
