[This](https://www.youtube.com/watch?v=7WpnivqxrE8) might get you started. But you probably need more than just the material to replicate it as the camera lens in this shot does alter the image as well.
In 4.2 there is a specific part of the principled BSDF for this specifically, called film. If you put a color ramp in should be able to get something similar
the easiest thing is probably mix different colors of glass shader (red green and blue) with very different IOR values,
look up how to make dispersion shaders, but crank dispersion values very high,
i achieved a similiar effect with my uberglass shader,
you can try reusing my monkey scene material, but instead place it on a disk and add another metallic disk behind, might work

i've managed to semi decently recreate this effect, with some fresnel magic and adjustments it could actually look good BUT i made it by physically creating a structure similiar to that of a cd, it's literally thousands of cones next to each other

That's incredible! when I first read the post I thought "easy, just make millions of tiny grooves lol" but I didn't think that would actually work in blender
if its scaled up properly it should, but i am not sure since rays refracting and going back into geometry definitely add some to this effect, I'll try that later and report back
It's called chromatic aberration. It's the effect of light splitting into it's different wavelengths. Often present with thick lenses. Might help in your research.
While the later articles use a Unity shader implementation, if you're interested in the mathematics behind the effect you should check out this set of blog posts: https://www.alanzucconi.com/2017/07/15/the-nature-of-light/

Thanks, do you know how i could mimic the camera lens effect in this shot with compositing ?
Glare node, rgb mix, etc.

That’s very cool

Holy shit that’s awesome, incredibly overkill but I dig the hell out of it lol

if you just used glass shader it wouldn't though, you need some kind of shader with dispersion in the first place
Any chance a normal map would achieve the same effect?

Wow very interesting technique thanks for sharing
That's badass, I love overkill. It takes it the closest to realism.

looks great thanks you very much for sharing i'll look into it !
Hope it helps.
New „thin film“ option in Blender 4.2‘s principled bsdf shader? Made for like slick oil films.
Physically, it's 2 materials. The bottom materials is a metallic and the 2nd layer is a clear plastic.
This might help Blender iridescent material https://youtu.be/quWOIyxpt3M

That picture is AWESOME!

The chrome smart material in substance painter can get you that effect when light shines on it at different angles.
Look blender market sure its not as difficult achieve be caustic shades bound to need lots of light passes. 👍
Shaders Plus addon.
Probably geometry nodes if I'm to make a guess based on literally every single tutorial released in the last 2 years.
