Yellow Green colors during the old master period had an inexplicable name. The would be called names like pink bice or green pink. Pink was referring to the yellow color made from Buckthorn berries that was called either Still de Grain or pink yellow. It is not known why this would be. The color name pink is derived from a European wildflower called pink. Its flowers were either a light true pink color or white and is consistent with our modern understanding of the color name. Why yellow would be called pink seems very odd although it is possible that since Buckthorn could also be used to make a red color that the name might have been used for that color and then applied to the yellow by extension as it came from the same source.
