RGBW LED strip, testing different whites

Three white peaks move left-to-right. #1 is warmer white (the 'W' component), #2 is cooler white (RGB combined), #3 is brightest white (RGBW combined). The background color changes every cycle: black (unlit), red, green, yellow, blue, magenta, cyan. The video was shot with a Nikon Coolpix S8200, with very low expose. The saturation and exposure were enhanced in Final Cut Pro. I hope the video reveals the differences between the 3 whites. UCS2912 GreeLed RGBW LED strip.
