I prefer the first one, but I think it has more to do with tone than colour. The orange in the second one is a medium tone, like most of the other fabrics. The first one looks more visually distinct and crisp, because the lighter fabric gives more definition. The second seems muddied in comparison.
I would be interested in seeing a light orange; it might give you the colour triad, while still having the tone differences that I appreciate in the first example.
