Colour is nothing but a human construct right? It’s nothing more than our brains creating the colour we see and assigning that to a particular light wavelength. The photoreceptors in our eyes pick up on the wavelength, and depending on the range of nanometers it’s between, is triggered to create the colour that is assigned to a particular nanometer based on how our brain has been trained.
Energy surrounding the body, known as the auric field, can be seen and felt. I believe it’s possible to tune into these energy wavelengths using our extrasensory perception and allow our brains to assign the particular colour that matches. Following this process a magnitude of artistic opportunities open up, allowing the aura to be read, deciphered and created into beautiful artworks!
