Actually it appears to have nothing to do with that. I suspect it's somehow messing with the hex-to-rgb conversions.
My guess after some experimentation is it does the following (assuming an explicit colour name lookup fails): 1. Divide the string into three equal parts corresponding to Red, Green and Blue respectively. 2. For each part, read from left to right, accept only valid hex digit (0-9|A-F|a-f), stop once two have been found, or end of the part is reached. Concatenate digits, zero pad and convert to integer value.
Using that formula: "roliasnoom" "rol", "ias", "noom" "", "A", "" 00, A0, 00 0, 160, 00
It certainly seems to hold true. Orin would indeed be black since it contains no hex digits and a scren grab confirms "roliasnoom" is RGB(0,160,0).
