Just the other day reading the book I found a more “tangible” and scientific explanation of how the colors influence us.
"Clearly, there is more to colour than meets the eye as even blind people can literally ‘feel’ different colours with their fingertips.
Colour is not just part of the object we see in the distance, it's a light wave coming right at us. Colour is simply energy. Energy influencing our feelings, our well being, and demanding a response.” A.Wright
If color is energy, probably there’s much more encoded in this energy from the plants and therefore we have such different experiences when facing a live color from the plant rather than a “dead” synthetic color.
Dyed with St. John’s wort.
