// 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.
