Color of tin boulder on map?

[Peanuts]

I'm trying to find a tin boulder to set up my drill, remember encountering 2 tin boulders somewhere.

All I know is that copper is a red square on your map, gold is yellow, iron is indigo, but I can't find tin.

tin looks almost like stone

Tin shows up like a light black square for me.

Your colours differ from mine. Copper = Orange, Tin = Black, Iron = Gray, Gold = Yellow and Scarlet = Red.
Really annoying that iron is the same colour as stone on the map tbh.
