Generally speaking a boolean condition is understood to be an "either/or" relationship; for example, something is hot or cold.
What's do you call a "one or more" condition, e.g. something that can have many colors?
To add a bit of clarification, in conversation most people understand Boolean to be an "either/or" proposition, whether there are two or more conditions, as when you ask someone to pick a single color of paint (red, green, or blue).
When discussing that with non-programmers, I find they perfectly understand that when I describe it as a boolean condition.
However, I don't seem to know what to call a "one or more" condition, for example, "pick any colors that you like: red, green, blue, yellow, orange, purple."
I find my self saying "non-boolean" which isn't all that useful.

Rubergly's answer gave me an interesting thought:
Boolean is similar to "dichotomous" and also similar to "binary" (1 or 0). Trinary means set of three... so is "polynary" a word, or is there something similar?
