[2] However, researchers have found that the blue color in some blue wines comes from synthetic food coloring. [3]
If defined as blue-dominated colors between blue and red, violet colors in Munsell's system would be classified as having the 7.5PB and 10.0PB hue, which is confirmed in visual experiments [6] The truly purple color, defined as being within the range of the red-dominated colors between red and blue, is sometimes confusingly labeled as red ...
It also gives the blue-red color of the grape variety Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, [4] and bilberries.
