I may be mistaken, but orange may be used...
It must be used on a three phase high leg, but it is NOT limited to that use.
The only colors limited for their use is green, green with yellow stripe, white and grey.
Please correct me if I am wrong.
(FYI: Brown-Orange-Yellow is commonly used on 480V with no high leg)
