The color of the emitted light

I still wonder why this game is so gray compared to some texture packs.

One reason is definitely The Emitted Light.

Why hasn't Mojang made the emitted light different colors yet?

In the game, it doesn't matter whether it's a regular torch, fire, lava, a copper torch, a soul sand torch, blue fire, or a redstone torch.

Everything emits a white, hospital-like light.

In addition, with the new fog in version 1.21.6, the game seems even grayer and sadder than before. Not to mention the colors of nature.
The colors of grass and leaves in most biomes are very pale. Like a sad, wet, and ugly autumn, or a drought in Minecraft or Pale Garden affects all of Minecraft.

Add Different Colors of The Emitted Light!!!
Please!
