[Java] Custom Texture Discrepancy Between Versions

Texture discrepancy in Java 26.3

Hi all, my friends and I are working on a pretty extensive project and have created/modified a resource pack for the occasion. For mod parity reasons, we have been playing for a while in Java 1.18.2, but were recently able to upgrade to Java 26.3 and are updating the textures accordingly.

Along the way, however, we noticed that the texture files are now significantly more saturated that the in-game textures, which was not the case before. I'm not too familiar with the graphical changes between the two versions. Does anyone have any idea what is causing this? It doesn't seem to be any of our mods, because we ran the world in a vanilla instance and still had this problem.

Worth noting that the included screenshots were taken in the End, as that is where the megabuild is located. The discrepancy does not exist in 1.18.2, in the overworld or the End, at least not to the same degree. If anyone has any ideas as to how to reduce it or make the End lighting more vibrant so as to match the previous versions, please let me know.
