There are special cells in your eyes called Short-wavelength (S) cones that help you see colors like blue and purple.
Imagine you have a box of crayons. Most kids use the red, yellow, and blue ones to draw. The Short-wavelength (S) cones are like the blue crayon, they're really good at picking up the blue parts of things you look at.
Now, think about how your eyes work when you're outside on a sunny day. Your eyes have little helpers called cones, and each one is good at seeing different colors. The Short-wavelength (S) cones are like tiny detectives who shout “I see blue!” whenever they spot something blue, like the sky or a blue toy.
Sometimes, when you look at something that’s not just blue but has lots of colors mixed in, your eyes use all kinds of cones together to figure out what color it really is. It's like mixing crayons on paper, red and blue make purple, so your Short-wavelength (S) cones help you see that too.
So next time you look up at the sky or play with a blue toy, remember: your Short-wavelength (S) cones are hard at work!
