Lighting, Happiness?

Colour, it comes from the spectrum of light... Which, while daylights don't contain the full spectrum of colours, the sun does. Now, the sun also makes people happy, coincidence? I THINK NOT!

Indoor lighting, the kind you see in cubicles does not provide full spectrum lighting. Do you see happy people in cubicles? no. Coincidence? I THINK NOT!

that is all for today
