“The color preference is a significant and effective symptom. It‘s effective in the sense that it can indicate or confirm a diagnosis in many cases. The color preference is a peculiar symptom expressing the inner state of the patient, which is the state of the remedy. And it‘s a very specific symptom. The table designed by Ulrich Welte is the most usable I‘ve seen so far. All colors are clear and accurately standardized, so it can be used without ambiguity.“
