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

What leds/driver are you using? – Gerben Mar 18 '16 at 20:09

I think you could use [`showColor`](http://fastled.io/docs/3.1/class_c_fast_l_e_d.html#a570df74cf09e6215c3647333d2b479a9) – Gerben Mar 19 '16 at 15:19

You can use fill_solid.
For example
fill_solid( leds, NUM_LEDS, CRGB(50,0,200));
Or
fill_solid( leds, NUM_LEDS, CRGB::Red);

Works fine. While **FastLED.showColor()** will not behave properly if you add delay after it, – mayid Oct 14 '20 at 02:12
