A couple(?) of weeks ago I ended with a lingering question:
“So, that is why the sky and feathers are blue. But are they, really?“

Like most things in the natural world, the answer is “it depends!” It would be way too easy and boring if the answer was simply “yes.”

Bonus Fun Fact: Colors appear differently, for different creatures, depending on how sensitive their eyes are. What appears blue or orange or red to me, may appear to be different to you. Certainly the colors we as humans see are different from other animals. Bees, for example, can’t see red. This is likely why they don’t obey stop signs. However, they can see into the ultraviolet end of the spectrum, which helps them find the delicious nectar of certain flowers.

Bonus Bonus Fun Fact: In humans, about 8% of males and 0.5% of females have some form of color vision deficiency, where they do not see certain colors as the larger population does.
