Looking at them side by side is making me realize how much I didn't realize I hate the top one
Well the top one is just a crude left-to-right gradient overlay with no regard for the shape whatsoever. You could slap that shit on any old shape and it would basically be the same, red on the left and violet on the right and that's it.
The bottom one is a nice smooth transition that actually follows the shape. That's why it's so much more pleasant. The hue change occurs continuously as your eye goes along the path.
Oh and the bottom one is a more balanced shape overall. The top one feels too tall. Maybe it's a golden ratio thing, I don't know.
I think purple should be the color that goes under the overpass, since it's the one our brain makes up between violet and red to turn our perception of visible light into a color wheel.
Sometimes I forget that purple is not a real but just a collective hallucination
Not all purple is faked. All onscreen purple is fake, but so is onscreen yellow and orange.
Indigo and violet are real and look purple to us. This is because they are moderately close to the blue frequencies so stimulate our blue cones and moderately close to double the red frequencies, so also stimulate our red cones.
There's no way for you to tell whether you're looking at something that's genuinely reflecting indigo or violet light into your eyes, or something that's shining a mixture of red and blue light at them.
If it's on a screen, it's definitely fake and not indigo or violet at all. Screens can only make red, green and blue light.
Any yellow or orange you see on a screen is also completely fake. It's just red and green light mixed up with no yellow at all.
If you're seeing it on an object, it's far more likely to be real yellow or real indigo/violet. Pigment and light don't mix in the same way at all.
