Colony/Pop requirements for luxury resources

[Teflon007]

How much of a luxury resource is required to maintain its bonuses? Because colonies frequently show shortages on luxury resources, is this an actual problem or does simply having a source grant all colonies the bonus?

If indeed a certain amount is needed per pop, I suggest the affected bonus show in red or light pink when you mouse over the colony bonuses tool tip to better track what colonies lack what.

My limited understanding is that colonies consume the resource (at a rate proportional to the population).

If the resource runs out, the colony loses the bonus.

So you have to be continually supplying the colony with the resource at a rate at least matching the consumption.
