declare upper;

AddLabel(1, Concat("IV% ", ivp), if ivp > 80
then Color.Green
else if ivp < 80 and ivp > 50
then Color.Yellow
else color.Red);

Hints:
a) Use 252 as input length for 1-year or 52-week IV percentile
b) You can change 252 to 189 for 9-month IV percentile
c) You can change 252 to 126 for 6-month IV percentile
