Help With Coloring LEDs. Arduino MEGA 2560 // WS2812B Strip.

The "Color" values of...

if (songmode == HIGH) {
fade_scale = 3;
Color.r = 3;
Color.g = 2;
Color.b = 0;
}
else if (songmode == NORMAL) {
fade_scale = 2;
Color.r = 3;
Color.b = 2;
Color.g = 0;
}

...Change the color, but it only serves in changing the color of the LEDs as a whole. I've tried addressing them individually with both of these forms:

leds[0] = CRGB(0, 0, 25);

leds[0] = Color.r = 0;

Neither of which have worked thus far.
