There is also a fourth value for alpha, as in #3 above5) <i>Color.red</i> etc. - there are several predefined static values: black, blue, cyan, darkGray, gray, green, lightGray, magenta, orange, pink, red, white, and yellow @Nick – JLabel’s Background and Foreground properties, and their corresponding getXYZ(),setXYZ() accessor methods, are common to all Java Swing components, together with several other basic properties (and their accessor methods).

In this particular case, java.awt.Color can be constructed in several ways:

1) Color(int) – the single integer RGB value you have reported in your comment

2) Color(float,float,float) – accepts three values between 0.0-1.0 (R,G,B)

3) Color(float,float,float,float) – as #2 above, with an additional 0.0-1.0 value for transparency (alpha)

4) Color(int, int, int) – as #2 above but the RGB values are specified as integer values between 0-255. There is also a fourth value for alpha, as in #3 above

5) Color.red etc. – there are several predefined static values: black, blue, cyan, darkGray, gray, green, lightGray, magenta, orange, pink, red, white, and yellow

You can cobble together highlighted sentences using this technique by aligning multiple JLabel objects in the figure. I don’t know if this is obvious as I don’t know Java, but you can change the gray background of the JLabel by defining a java.awt.Color object and using setBackground:

mycolor = javaObjectEDT(‘java.awt.Color’, rgb_code)
setBackground(jLabel, mycolor);

The rgb_code is an integer that seems to be correspond to RGB as follows:

256^2*(0-255 red level) + 256*(0-255 green level) + (0-255 blue level)

So black = 0, and white is 256^2*255 + 256*255 + 255. You can cobble together highlighted sentences using this technique by aligning multiple JLabel objects in the figure.
