Sulfur and cinnabar gradient

Currently, the sulfur cave contains two main types of blocks: sulfur and cinnabar. However, since sulfur is yellow and cinnabar is red, the boundary between the two blocks looks somewhat unnatural.
Therefore, I believe that either the texture should switch to a gradient when the two blocks are adjacent, or a new gradient block should be added within the sulfur cave (automatically resulting in more yellow on the side adjacent to sulfur and more red on the side adjacent to cinnabar).
