How to get RGB value from hexadecimal color code in java

Question

I have a decimal color code (eg: 4898901). I am converting it into a hexadecimal equivalent of that as 4ac055. How to get the red, green and blue component value from the hexadecimal color code?

Answer 1

Assuming this is a string:

// edited to support big numbers bigger than 0x80000000
int color = (int)Long.parseLong(myColorString, 16);
int r = (color >> 16) & 0xFF;
int g = (color >> 8) & 0xFF;
int b = (color >> 0) & 0xFF;

Answer 2

If you have a string this way is a lot nicer:

Color color =  Color.decode("0xFF0000");
int red = color.getRed();
int blue = color.getBlue();
int green = color.getGreen();

If you have a number then do it this way:

Color color = new Color(0xFF0000);

Then of course to get the colours you just do:

float red = color.getRed();
float green = color.getGreen();
float blue = color.getBlue();
