Opening JEI and searching for water (or any similarly drawn substance, such as Mek's chemicals) and changing the dark mode changes the shading of the sprite drastically.

Forge: 39.0.64

This does not appear to be fixed as when using the method dump thing it provides mezz.jei.library.render.FluidTankRenderer:drawTextureWithMasking as the method for JEI's fluid rendering, but the one that is blacklisted by default is mezz.jei.common.render.FluidTankRenderer:drawTextureWithMasking
