First of all: Great mod, I love it.

However, the Cobalt tile colors are a bit to saturated IMHO, esp. the Metal Tiles. It's great for heat transfer (if you don't have Aluminium, screw this seed!) but then it stands out way too much in the middle of your base. Like every other tile has a nice subtle hint and fits well together as a whole, and then there's the way too prominent deep blue Cobalt block in the middle of it.

Would it be possible to tone down the tint of Cobalt Metal Tiles (and probably Mesh Tiles too)? I think a subtle sky blue would fit much better than the deep blue.
