I am wanting to add user color control to my VU meter,

I am wanting to add user color control to my VU meter, I was wondering if anybody could tell me where in the library CRGB::-COLORNAME- i located so i can see how it works and decide how to dynamically change color.

HTMLColorCode is here: https://github.com/FastLED/FastLED/blob/ccf12263ce06218302c7bdcb7879a6e90122266e/pixeltypes.h#L568

@Jason_Coon I have now found that, I see that it is 3 uint8_t unioned together. I am not really sure how to pass this into a function. would you be able to help me?
