// FastLED v2.1 provides two color-management controls:
//   (1) color correction settings for each LED strip, and
//   (2) master control of the overall output 'color temperature' 
//
// THIS EXAMPLE demonstrates the second, "color temperature" control.
// It shows a simple rainbow animation first with one temperature profile,
// and a few seconds later, with a different temperature profile.
//
// The first pixel of the strip will show the color temperature.
//
// HELPFUL HINTS for "seeing" the effect in this demo:
// * Don't look directly at the LED pixels.  Shine the LEDs aganst
//   a white wall, table, or piece of paper, and look at the reflected light.
//
// * If you watch it for a bit, and then walk away, and then come back 
//   to it, you'll probably be able to "see" whether it's currently using
//   the 'redder' or the 'bluer' temperature profile, even not counting
//   the lowest 'indicator' pixel.
//
//
// FastLED provides these pre-conigured incandescent color profiles:
//     Candle, Tungsten40W, Tungsten100W, Halogen, CarbonArc,
//     HighNoonSun, DirectSunlight, OvercastSky, ClearBlueSky,
// FastLED provides these pre-configured gaseous-light color profiles:
//     WarmFluorescent, StandardFluorescent, CoolWhiteFluorescent,
//     FullSpectrumFluorescent, GrowLightFluorescent, BlackLightFluorescent,
//     MercuryVapor, SodiumVapor, MetalHalide, HighPressureSodium,
// FastLED also provides an "Uncorrected temperature" profile
//    UncorrectedTemperature;
