RGB value in decimal. Decimal 8421504 = hexadecimal 808080 = RED hex. 80, GREEN hex. 80, BLUE hex. 80 = RED dec. 128, GREEN = dec. 128, BLUE dec. 128

I think it's important to note, that while decimal 84215404 = hexadecimal 808080 and Mofi is technically right about the red, green, and blue hex values above, UltraEdit syntax colors do not use the standard hex order RGB, but instead a reverse order of BGR (at least when compared to the hex order in HTML files.)

For example, a decimal number in a wordfile 54509 = hexadecimal 00D4ED, which will translate to RED hex ED, GREEN hex D4, and BLUE hex 00. This would be RED = dec. 237, GREEN = dec. 212, and BLUE = dec. 0.

I hope this makes it more clear.

Thanks, rhapdog. The example in my answer was not really good.

The order is BGR because that is the byte order used by the RGB macro of Visual C++ which produces the 32 bit unsigned color value.

In C/C++ the macro does something like that

DWORD COLORREF = ((DWORD)BLUE << 16) | ((DWORD)GREEN << 8) | (DWORD)RED;

or better readable for non programmers:

Color = BLUE * 65536 + GREEN * 256 + RED

As a C/C++ programmer I automatically read the bytes from right to left to get the RGB values. And when I'm working with HTML and CSS I automatically read the RGB values from left to right. Thanks again rhapdog to make it clear for all non C/C++ programmers and HTML writers.
