Nuggets use a different ingots color palette

Problem:

The iron and gold nugget texture uses a different color palette than the iron and gold ingot texture

How to reproduce:

-Take iron nugget, gold nugget, iron ingot and gold ingot

-Observe iron nugget and iron ingot texture (do the same for the gold variants)

Expected:

-Iron nugget has the same color as iron ingot (same with gold variants)

Observe:

-Iron nugget looks blueish while iron ingot looks silvery

-Gold nugget has a different outline than gold ingot
