This was a Facebook post to a synesthesia group but I can't share it because the group is private.
Okay, I'm really hoping to find someone who understands what I experience here. So, pretty much most people can experience the effects of chromostereopsis, which is one color appearing closer in depth to another by side by side comparison. It's a big pop-art kind of thing. Like I said, most people will see the red appearing to "float" in front of the blue in a field of depth, some people don't, and some people have a reverse effect of the blue appearing in the front. It has to do with the binocular vision of depth perception, and colors on the opposite side of the visible light spectrum retracting in the eyeball at different angles.
So this is not a synesthesia type thing in its common experience I think? But, even in these examples I attached, you'll mostly likely see it "popping" off the screen just a bit. but to me, if I hold my phone at about arms length, it appears like the red is a good 2 inches closer to me than the space my phone is at, and the blue is a good inch behind my screen. Like the red is floating and a hole has been punched through my screen with the blue covering the hole from behind my phone. It gets more pronounced when I'm tired. It's not just red and blue for me. It's every saturated or vibrant color. They all have their own depths comparatively to each other. It varies depending on whether it's an electronic screen, plain LED lights, a matte vs shiny surface painted, and it's the worst(biggest depth difference) if it's a physical object viewed under sunlight.
It's very distracting and my adhd made elementary school difficult (colorful decorations and posters EVERYWHERE you guys). When I was in elementary school, the first time I ever attempted to ask if other people see what I see, I asked the teacher why the red marker words were floating on the dry erase board, but the others didn't (except the purple marker) and my teacher thought I was just being funny and didn't answer me. So I didn't ask again. In high school I learned about the word synesthesia, and thought perhaps this is what it is, but years of googling color and depth synesthesia has brought me nothing but some people claiming colors belong to the left or the right, or the terms chromostereopsis, and tetrachromacy.
Tetrachromacy (being a tetrachromat) would mean you have a fourth cone in your eyes that would pretty much allow you to see more color. You aren't necessarily seeing what other people don't, but more like, you can see the in between colors and distinguish them better than people who aren't tetrachromats. It's like how trichromats (most people) can distinguish colors far better than dichromats or trichromats with anomalous mutations in one type of cone (colorblind people). So maybe I'm a tetrachromat, maybe not? And if so, maybe it also translates into amplifying the chromostereopsis effects vibrant colors have? I've read one article where someone briefly explained seeing colors like me before.

But I don't believe seeing such a pronounced difference in depth like that, is just what everyone sees, because every time I talk to people about it, they don't understand what I'm talking about. I'm talking, anywhere from a millimeter to 6 inches of floating or receding colors on a completely flat surface. (And the green and red LED gas prices on roadside signs are the only ones that specifically feel like almost 1 foot (daytime) to 4 feet (nighttime) of a different depth between each other)
If anyone here doesn't really get what all I'm trying to say, I do know that a lot or people with color-related synesthesias claim to see the colors at a certain depth in their vision or as a superimposed layer over the number letter or word they are looking at, it's kind of like that for me. It's flat and 3d in my head at the same time for me. Or if you've ever had chromadepth glasses on for a coloring book or crayola chalk art kit, you'll know what I see, because it amplifies what I see by a lot more, I've tried them on.
If anyone has any feedback or insight to what I see, please, please let me know. I've had the pleasure of showing the colorvision glasses to an art professor, a psychology professor, and my optometrist, and while they all found it interesting and whatnot, I don't have a definitive answer of why I see such a depth.
