Cold Color Grading Palette for Snowy Biomes

This would be a hardcoded palette change, so it wouldn't cause any FPS drops or performance impact on Java Edition and This would make the biomes appear icy blue like in the Vibrant Visuals.

You recently added the "End Flash" effect to Java Edition, and it does not cause any performance or fps rate drops, showing that small, atmospheric graphical improvements are a priority. Adding varied snowy shades (e.g., a colder, blueish palette for Snowy biomes would greatly increase immersion without changing the core gameplay.

Inspired by "Vibrant Visuals": This feature are already exist in the "Vibrant Visuals", Bringing this aesthetic to the base game is a natural next step for modernizing Minecraft's look.

No Performance Impact: Since this is a simple palette change (hardcoded color shifts for specific biome IDs), it would not cause any FPS drops or performance issues on Java Edition.
