  Irradiance and Duration of Exposure to Light
  Green light close to the 550 nm wavelength suppresses melatonin similar to blue light.

• Effect of Light Wavelength on Suppression and Phase Delay of the
  Melatonin Rhythm
  Exposure to short wavelengths 525 nm (green), 497 nm (blue/green), and 470 nm (blue)light resulted in high melatonin suppression.

• Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor

In 2001 a flagship academic study was released that indicated blue light can impact sleep/wake cycles in humans. Blue light disrupts your sleep, however it has also been shown that green light can too. Studies have shown that green light also disrupts melatonin production.

In conclusion, this study characterizes the wavelength sensitivity of the ocular photoreceptor system for regulating the human pineal gland by establishing an action spectrum for light-induced melatonin suppression. The results identify the 446–477 nm portion of the spectrum as the most potent wavelengths providing circadian input for regulating melatonin secretion.
