According to Oracle's site, the class Color has a constructor that accepts a single int value which represents an RGB value. http://download.oracle.com/javase/1.4.2/docs/api/java/awt/Color.html#Color(int)
An RGB color is actually three different numbers ranging from 0-255. So combining them together to make one int would look like this:
White 255,255,255
White 255255255
Right? So I pass this to the constructor and get a vibrant teal color. What am I doing wrong? What haven't I understood?
From Convert RGB values to Integer
int rgb = red;
rgb = (rgb << 8) + green;
rgb = (rgb << 8) + blue;
To pull values out:
int red = (rgb >> 16) & 0xFF;
int green = (rgb >> 8) & 0xFF;
int blue = rgb & 0xFF;
Javadoc from the other constructor:
Creates an sRGB color with the specified combined RGBA value consisting of the alpha component in bits 24-31, the red component in bits 16-23, the green component in bits 8-15, and the blue component in bits 0-7. If the hasalpha argument is false, alpha is defaulted to 255.
So, you just need to construct the int using bit operations.
Color col=new Color(255,255,255);
Label l1=new Label("I got this color");
//setting the color in label background
l1.setBackground(col);
