Describe the problem requiring a solution

Currently we aren't using the original hues for some of the colors because they were indistinguishable from certain terrains - e.g. orange with wasteland. But, I find orange and yellow to be too similar. Maybe we could make the orange color a bit more red? We will have to take into account that the color cannot be the same as any terrain on the mini-map.
