wavelength:: 380-420 nm
emotion:: fear
the shortest visible wavelength, bordering ultraviolet — the edge of perception
evolutionary signal: high-energy radiation, cellular death, the boundary of the known
properties
highest photon energy in the visible spectrum
UV radiation (just beyond violet) induces apoptosis — programmed cell death
the color of bruising: blood pooling under skin, tissue damage
historically associated with royalty, mystery, the sacred — things beyond ordinary reach
in nature
UV radiation: invisible, dangerous, causes DNA damage and cancer
bruising: the visible aftermath of trauma
twilight violet: the last light before total darkness
rare in nature — few organisms display violet, reinforcing its strangeness
in prism
unknown threat, unverified source, irreversible action, boundary warning
the color of the edge — where the cybergraph ends and the unknown begins
