Temperature overlay: more bands for cold temperatures?

[Theoretician]

With the introduction of the Rust Biome, I think it would be helpful to have more bands for cold temperatures in the Temperature Overlay. I also find the current bands of blue are very difficult to distinguish from each other, and this could be changed.

For example, it would be good if there was a clearer visual distinction between the following bands: -40 to -30.1, -30 to -20.1, -20 to -10.1, and -10 to -0.1, in addition to the existing "chilled" band (0 to +9.9). 

This would be especially helpful in the early game, when I find myself breaking into the Rust Biome and trying to avoid heating it up too quickly.

I think it may be helpful to have particle effects to display extreme cold and hot temperatures. For example something that is lava hot would show a bubbling effect, and something super cold may sparkle.

Or if we had two sliders for upper/lower level of what the overlay considers hot/cold. This way we could set them to some values for looking at any reasonable range of temperatures depending on what it is we're trying to look at.
