Historically, colours associated with royalty and high status were almost always the colours that were hardest and most expensive to produce reliably — the association was fundamentally economic before it became purely symbolic.
Tyrian purple's restriction to Roman and Byzantine imperial rank is one of the best-documented examples of a colour's cost directly determining its legal and social restriction.
Clothing and status · Rome and Byzantium
Sumptuary laws — legal restrictions on who could wear which colours and fabrics — existed in various forms across medieval and early modern Europe and parts of Asia, generally reserving the most costly dyed and richly coloured cloth for the highest social ranks.

Once synthetic dyes made formerly rare colours widely affordable from the mid-19th century onward, many of these older status associations weakened, even though some (such as purple's link to royalty) persisted culturally long after the economic reason had disappeared.
Changing meaning · 19th century onward
Rank colours do not all arise the same way, and the surviving evidence separates at least three routes. The first is cost: murex-dyed textile found at Timna is treated by its excavators as evidence bearing on who formed the elite of a mining community. The second is language following cloth: 'scarlet' in English first meant a top-quality fabric and only later a colour, and 'crimson' reached every European language through the Italian silk trade from the name of the kermes dye. The third is plain regulation, in which a rule reserves a shade whatever it costs to make. The three overlap, but they fail differently: cheap dyes undo the first, while the third lasts for as long as the institution behind the rule does. 1, 2
| When | Where | What happened | Sources |
|---|---|---|---|
| Late 11th to early 10th century BCE | Timna Valley, southern Levant | Purple-dyed fibres at a smelting camp are interpreted, with the high quality of the other textiles there, as evidence of social stratification among the people running the mines. | 1 |
| Mid-13th century | England | 'Scarlet' is recorded for a rich cloth; the word had named quality before it named a hue. | 2 |
| By the reign of Edward III (1327–77) | England | Judges' dress was more or less settled on the model of what was correct at the royal court: violet for winter, green for summer and scarlet for best, with cloth granted by the Crown. | 3 |
| 1550s | England | 'The purple' is in use as a figure of speech for imperial or royal power. | 2 |
| 1840 | Britain | Queen Victoria married in a white satin court train trimmed with orange blossom in place of the crimson velvet robe of state, presenting herself as a bride and not as the monarch. | 4 |
| 1862–74 | China (Qing dynasty, Tongzhi period) | A dragon robe now in London was embroidered to appear bright yellow, a colour of which certain shades were restricted to the emperor and his immediate family. | 5 |
Claim: Cheap synthetic dyes ended colour as a marker of status.
Evidence: Only half supported. Perkin's mauve was cheaper than natural purple and became a mass fashion within three years of its discovery, so the price barrier did fall. Colour reserved by rule carried on regardless: a violet robe was proposed for English County Court judges in 1915 and made compulsory in 1919, more than half a century after purple had become affordable. 6, 3
