Making ship market comparison colors colorblind friendly (#5715)

* Adding compare colors

Adding two new colors: compare_worse and compare_better
Worse is the same as warning_300, which was used previously for the ship market comparison.
Better became a saturated blue.
Updated the ship market to use these two.

* Changing to already existing semantic colors

Better now uses accent_300
Worse reverted to warning_300
