Took me quite a while to find it, too.
I was distracted by the fact that the available letters contained combinations such as -able (possible ending) and over- (possible start) and, quite possibly, more than the two words ending in '-o(u)r/-o(u)red' that I had already seen.
Finally it turned out to be not an English word at all, but a French one, not following any pattern of normal English word formation.
Excellent.
