You're absolutely right, our body most definitely reacts in different ways to different wavelengths of light.
A specific green has been shown to help reduce pain. [1] 525 nm seems to be the magic wavelength in this particular case.
I'm a chronic acute pain sufferer. I'd love for something as simple as an array of green LEDs to help with my pain. I keep meaning to get a large breadboard, a bunch of LEDs, and make such a device.
I wonder what effects other wavelengths might have? Would lights help sleep if they matched sunset darkening to night time through purple and indigo? It's fascinating stuff.
I have an amibilight built around WS2812 LED strip and esp8266. I use it to display a colorful rotating gradient during a day and as a night light with red color.
Small Haskell program using reactive-banana-automation feeds simple nodemcu firmware every second with UDP packets. It's quite easy to build RGB light this way as only one signal wire is required.
