This has been bugging me for a while. Why the material colors in react-three-fiber appears to be dull than in threejs
Threejs
react-three-fiber
r3f uses correct gamma in a srgb colorspace and automatically converts colors and textures to srgb. this is similar to what aframe does. threejs has incorrect gamma settings in a linear colorspace, which is not very usable. wrong gamma is the #1 reason for cheap, plasticy looking 3d scenes. see: https://www.donmccurdy.com/2020/06/17/color-management-in-threejs
if you want a linear colorspace, just do: <Canvas colorManagement={false}>
and now your colors will match.
