how to convert rgb color to hex color - kotlin

This is what I do

val color = String.format("0XFF%02x%02x%02x", r, g, b)

this returns me a string "0XFFhexcode" I want to convert it to long, to store it and then use it as a color

color.toLong()

I have the following error

java.lang.NumberFormatException: For input string: 0XFFhexcode

You can do it simply like the following:

val rgb =  Color.rgb(red, green, blue)
val hex = String.format("#%06X", 0xFFFFFF and rgb)
