Dirt paths use the same color as dirt on maps

The Bug

Dirt path looks identical to dirt on maps, and does not have it's own lighter brown color. See my attached images for a visual representation.

Steps to Reproduce

• Summon a square of dirt path and dirt.

   /fill ~3 ~ ~3 ~9 ~ ~9 minecraft:dirt_path
  /fill ~-3 ~ ~-3 ~-9 ~ ~-9 minecraft:dirt
  

• Obtain an empty map and use it.
• Look at the color of the dirt path and the dirt on the map.
  → Notice how dirt path uses the same color as dirt on maps.

Expected Behavior:

The expected behavior would be that the dirt path would not use the same color as dirt on maps.
