On a map, quartz blocks and slabs appears the same as stone- a dark grey. This has been a major setback in my pixel art build, which mainly featured quartz. I wanted to be able to see the pixel art on the map, however, when I opened up the map all the quartz was grey instead of white, ruining my large pixel art. It would be great if this was changed, as I do not want to rebuild the art as it took me a long time.
