Over The Years,

there have been all manner of studies now dismissed as pseudoscience,

illustrations The Principle’s of Light and Color by Edwin D. Babbitt, (New York: Babbitt & Co., 1878),

the science is called chromotherapy, the correction of physical and psychic imbalances through exposure to antidotal hues, it is now widely dismissed,

Edwin D. Babbitt’s The Principles of Light and Color (1878) was not the first influential book on modern chromotherapy, for example, this 1876 treatise on blue light written on blue paper,

and to say it dealt with the subject lightly is a understatement, 

the volume ran to over 600 pages!

it is easy to dismiss Babbitt as a chromophilic quack operating in prismatic isolation. Chromotherapy was once a widespread practice. At the Salpêtrière Hospital in Paris, Charles Féré tinted the panes of hysterics’ cells with violet glass; shell-shocked soldiers were placed into James Turrell–like colour wards to cool their nerves during World War I, and now modern science has come full circle, from dismissing Chromotherapy to now embracing it, in articles like this, from Mental Health America, perhaps The Principle’s of Light and Color should be given a re-read?
