I was on a recently made Boeing plane where the color of the lights changes from a blue at takeoff to a warmer color at landing. I liked the idea and wanted to integrate into my window. I wanted the colors to correlate to the time of day and maybe the color temperature of the sky.
I did some research and found some references to color temperature given the sun angle, but they were symmetric. I tweaked it for aesthetic reasons, added some bluetooth control and a sound sensitive microphone.
At dawn the window casts a blue, midday a white to yellow and at evening a yellow to red at sunset.
The hardware was simple to setup using the strips of neopixels.
