Is there a way to call the color as an assignable variable in a CRGB line:
leds = CRGB:: Orange;
replaced with
myVariable = Orange;
leds = CRGB:: myVariable;
if so what would be the data type?
PaulRB answered my same question here.
Also, one of the sample sketches shows how colors are defined and passed to functions:

FastLED.setBrightness(BRIGHTNESS);

void cylon(CRGB streakcolor) {

for (int i = 0; i < NUM_LEDS; i++) {
leds[i] = streakcolor;
FastLED.show();
fadeall();
delay(10);
}
// Reverse
for (int i = (NUM_LEDS) - 1; i >= 0; i--) {
leds[i] = streakcolor;
FastLED.show();
fadeall();

}
}
// ========================== fadeall ==========================
void fadeall() {

}
}
Perfect! Thank you!
