Colours on Shade sometimes mean different things to what one would expect.
Notably, the five sapient species all have differently-coloured blood, meaning that red is not universally associated with blood.
Because of this, in the northern hemisphere, gold (and brown; voks blood isn't too different in colour from feraisai) is a colour of death, danger and other gothic things.
In the south, gold is more likely to be associated with the precious metal.
Silver and grey are associated with old age, too.
In the northern hemisphere, where red dyes are historically hard to come by, it's more likely to be seen as lucky, luxurious or generally positive.
