Factory palettes, second pass

One color family per factory type for its walls, floor and machines, so a sawmill never looks like a smelter. Each factory has its own hue, and materials differ by hue, not only by how light or dark they are. Pick, swap or tweak any swatch.

Input stockpile stripe#5FA347unchanged, clearly apart from belt yellow
Output stockpile stripe#DE7D33orange, between the old amber and red-orange, clear of belt yellow; the machines' output markers follow
