I am not a taxonomist, but I can confirm it. Further, I wouldn't suggest asking a taxonomist as the opinions will be inconsistent.
For reference, you can check out my color pigments page at: http://www.nascentorchids.com/color_pigments.html also check out this: http://www.nascentorchids.com/color_designations.html This will generally outline what you are looking for. But keep in mind, it is entirely possible to have a plant with normal coloration but without anthocyanins because there are also carotenoids which have colors typically associated with flavonoids.
