Lighting per object or conditional

Hi there, I am getting different designs ready to be exported from blender to gltf and three.js with different materials and textures from around the world. These are supposed to be seen together in one scene. Some of them have texture and some are just principal. In result, some of designs come too dark and some too bright and it is very difficult to set all the textures and materials as the same, one by one. Is there anyway that I could set a lighting per object in blender or conditional in three.js so that I could mange them more easily? Or any other trick that could work in here?
Thanks,
A.

Tbh, out of all your options, the easiest one would to just fix the materials in Blender first. Doing asset modifications in code is kinda a last resort in terms of maintainability and flexibility.

(Selective lighting itself is not supported by three. Also this.)
