alt Hacker NewsEarthly colored clothing was not normal. Sometimes it might be forced on slaves, but humans like colors and dying clothing is a tiny part of what is needed to make a garment so anyone allowed to would do it.
of course we have a lot more colors available today, but there is every reason to think they would use all the color they could. Some of the colors decay fast (lasting longer than the garment if in use but not surviving to today if the garment was stored). Mostly this is something not written about in history so we have to guess but we have plenty of reason to think color was common.
There's a whole lot of pictorial evidence from medieval times and it typically shows quite a bit of fancy colored clothing. Even traditional "folk" attire, that would've been restricted to cheaper choices, is not really all that brownish. Modern chemical dyes were only around starting in the mid-19th c. or so, hence prior to that you got a somewhat poorer color selection, but some variety was absolutely available.
