One Orange = price of one cup of coffee.
Red=1/10 of an Orange.
Orange=10 Reds.
Yellow=5 Oranges =5 cups of coffee.
Green=10 Oranges=10 cups of coffee.
Blue=50 Oranges=50 cups of coffee.
Violet = 100 Oranges =100 cups of coffee.
Indigo=500 Oranges = 500 cups of coffee.
While we leave the exact prices of most daily items at player discretion, we would prefer it if prices were kept at a reasonable distance between most extremes. It’s all right to assume rent as 2 Indigos [1000 Oranges/cups of coffee], but it’d be a bit puzzling to see it downed down to 2 Reds.
In the beginning [until citizens established a financial system], money was handed down by deities liberally. Paradise was sadly lost. Potential solution? Get your character earning their keep! Either through the practice of a craft, composing mercenary guilds, stealing, bribing, etc – the choices are both endless, and yours.
[aid]: Yes, polychromatic thinks of the children! And no, unlike eljay, it won’t cut down on your pr0n.
To this extent, all children and physically-reflective elderly shall receive free housing and feeding. Additional costs can be covered through good ol’ lying, cheating and stealing, thank you.
As a bottom line: if a character can do something, anything, we expect a job to be assumed, and not stressed over. The money in and of itself is more useful as a plot device, and should not have you concerned over your characters' personal welfare. If you're not comfortable / can't accommodate the job/money situation, please feel free to disregard it completely. A player can choose to have their character discover an abandoned home in which they can live for free (utilities such as electricity and water are free in the City) or they can have an income of secretive "illegal" nature.
