Well I have then to confess you should have the means to purchase such an equipement but still ! It is still possible. Multiples examples confirm this strategy : the celts had refined armors and weapons, saxons too, german tribes also... Landknecht in medieval times had the authorisation to wear fancy and bright colors (normaly only reserved to nobility) to appear as an elite warrior troop (which was the case).
If the dude was rich or trying to pretend as much why leather? Why not metal? Anyone who was actually worth a lot would be wearing metal, so who would you kid with some leather?
Bright colours were not at all reserved to the nobility. Many bright colours were very cheap, and it's a modern convention that we think of medieval people as wearing very drab clothes. Purple might have been insane (go squish a thousand of a very specific type of shellfish and you can dye a shirt) but Red,Blue,Green, yellow, all bright, were cheap and could be obtained by easily accessible sources. Medieval clothing was Garish.
Dear Innocent Flower,
Sorry but once again I'll have to contradict you.
Firstly (about the third picture with the leather protections), I just said it was important to be beautiful on a battlefield to impress, but of wourse within their budget. Why no metal ? For a lot of reasons : because it fits the cultural design of the roman army, because leather is much more confortable than iron armor, because it's cheaper (you're not either poor nor rich you could be in middle class so affording an armor might be out of your reach but not a fancy leather garment).
Now about colours : where are your sources ? I am basing my affirmations on the work of Mr. Michel Pastoureau a renown french historian specialised on colours (you may check on the internet his books). So as you might know medieval societies in western Europe where highly codified also some colours were reserved for certain people because of the church of the ruling nobillity.
About those bright colours you were refering, this idea might be based on the assumption you had after seeing some pictures of this time period. However you have to remember that those clothes were often ceremmonial and were not "every day" clothes. Indeed, they are still more colorfull than one can imagine (even paysants and so on) but not necessarily bright because it was expensive (as an example, for the red, two ingredients could be used : garance, which was very dark but cheap and kermès, which was very expensive but bright). And even for the colours which were affordable, one may not be allowed to wear it according to your statut (a noble just can't be confused with a anybody no matter his wealth). This depends on the country : if I remember well some shades of red were forbidden in England (my source is the Shakespeare Globe museum in London).
Another example: clothes that were in contact with the skin had to be natural or white.
In the late medieval period, the french king for example published the "sumptuous laws" which clarified which colour may be used by whom.
Finaly, the example about the Landknechts should suffice to prove that some colours were not accessible to everybody, because why the priviledge then ?
Always glad to help,
