Turning all LEDs on (FAST.LED) In Fast.Led lib for arduino there is a code to turn off all leds

FastLED.clear ();


Is there also a shortcut to turn all LEDs ON, and with a specific color
You can use fill_solid.

For example

fill_solid( leds, NUM_LEDS, CRGB(50,0,200));


Or

fill_solid( leds, NUM_LEDS, CRGB::Red);
