different grimstone tiles texture

I personally love the new grimstone block set. the textures and style are great, and there is so much potential for cool new builds. however, the texture of the new grimstone tiles looked a little off. maybe its just me, but the mix of darker and lighter tiles seemed a little weird. the texture might be better if the light tiles were a little darker, and the transition between the different tiles on the block was slightly less sudden. every other block in the set was really good, this is just an idea I had.
