FPC, Lazarus LCL and fpGUI does the same - in the frameworks and
application code, hex values are always used for colors.
My comment was relating to when such values or properties are streamed
to a file. MSEgui is in the same boat. In this situation, the color
values are then persisted as integer values. See MSEgui's stat files,
FPC's ini output, Lazarus's lfm files etc as examples of what I mean.
Other language frameworks tend to save color values as individual RGB
channel values, or as a large single hex value.
For example, let look at Java...
======================================================
import java.awt.Color;
public class Test {
public static void main(String[] args) {
Color c = Color.CYAN;
System.out.println(c.toString());
}
}
======================================================
Output:
> java Test
java.awt.Color[r=0,g=255,b=255]
FPC and Delphi based applications would output the value 65535 (if it
used RRGGBB format) or 16776960 (if it used BBGGRR format).
Of all these examples, I know which format I find easier to read and
understand.
