What type of variable do I need to hold colors?

Need Help With My Project
1

I have these constants:
//COLOERS
#define BLYNK_GREEN “#23C48E”
#define BLYNK_BLUE “#04C0F8”
#define BLYNK_YELLOW “#ED9D00”
#define BLYNK_RED “#D3435C”
#define BLYNK_DARK_BLUE “#5F7CD8”

And I need to assign a variable to one of them, like:
if (heatISon) {
LEDcolor = BLYNK_GREEN;
}

I’m not sure how to set up the variable LEDcolor so that later (only occasionally) I can sent it to BLYNK like
led_heat.setColor(LEDcolor);

String works:

// set color of temp display
  String color;
  if (temperatureF < alertTemp) {
    color = "#04C0F8"; // BLUE;
  }else if (temperatureF < 70) {
    color = "#23C48E" ;  // GREEN 
  }else if (temperatureF < tooHot) {
    color = "#ED9D00" ; // YELLOW 
  }else {
    color = "#D3435C"; // RED 
  }
  Blynk.setProperty(V1, "color", color);
