What's this numeric notation called?

add(new CustomLabelField
("Please enter your credentials:", Color.WHITE, 0x999966, 0));

What is that 0x999966?

I want to place this color there so how can I convert it? I just need an online tool that will convert it for me but I don't even know what it's called! :D

link for more info

Thanks!

Edit: OK, so this is called a hexadecimal number, but I still don't know how to convert something like "#716eb3" to the notation accepted by the CustomLabelField constructor. Any help?

If it's C#, the format expected by the CustomLabelField constructor is most likely System.Drawing.Color that uses the ARGB format.

“The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). The alpha component specifies the transparency of the color: 0 is fully transparent, and 255 is fully opaque. Likewise, an A value of 255 represents an opaque color. An A value from 1 through 254 represents a semitransparent color. The color becomes more opaque as A approaches 255.”

Converting the ARGB format into a System.Drawing.Color can be done as follows:

Color myColor = ColorTranslator.FromHtml("#FF999966");

  1. In many programming languages, numbers prefixed with 0 are octal and with 0x are hexadecimal.

  2. Search for Hexadecimal to Decimal or Hexadecimal to RGB converters.

It looks like it might be in Java.

First, take the substring to remove the # prefix, then use Integer.parseInt("9999966", 16): that's parseInt with the radix for the base (see Integer documentation). Something along these lines:

String colour = "#716eb3";
colour = colour.substring(1,colour.length()-1);
add(new CustomLabelField ("Please enter your credentials:",
     Color.WHITE, Integer.parseInt(colour,16), 0));

Looks like a hexadecimal representation of a RGB. For example with #716eb3:

add(new CustomLabelField
("Please enter your credentials:", Color.WHITE, 0x716eb3, 0));

Hexadecimal, as in, base 16. If 0x999966 is indicating a color, then it's usually encoded such that each two hex digits encode a color (as RGB), so it's 0xRRGGBB.
