All you need in life is a color picker willing to expose you to the unbounded madness we call color vision.
what is even happening here 😨 wheres the circle with the triangle inside we all know and love..
The circle and triangle are a lie we tell ourselves to cope with the ugly reality... Now this-- this is the real deal!
In seriousness, this is oklch.com, a color picker for the OKLCH color model.
There are whole several hour lectures one could take in color science and theory, but to keep it short: the set of colors we can see, the set of colors monitors can display, and the set of colors computers can model are three circles that only somewhat overlap.
In this case, if I wanted this color
but in red, I could just go of Photoshop and move over the hue slider, getting this as a result:
Which is.. acceptable, but not as "bright" and "vibrant" as the green I had. Looking at the graphs in the OKLCH color picker, we can figure out why:
It tells us that a red with the same luminosity and chroma as this green is out of gamut—that is, it cannot be displayed by this monitor.
In this case, you can use the edges of the graph to find the color that is closest to what you want. You can, for example, keep the chroma but sacrifice lightness,
keep the lightness but drop the chroma,
or a bit of both, which is what the common HSV triangles already do.
But I like to know when it happens, y'know?
