Realistically the problem is that if isRGB gets anything other than an array or string, it treats it as an object, and trying to access properties (
c.r) on null throws an error.I shied away from really checking the type; it's possible to pass numbers, etc.. as well as arrays or objects of the wrong shape - execution stays alive but the user might get weird results. It's only null and undefined where a fatal error will occur and it's nice to give the user an indication of why.
