Delphi TColor RGB is Really BGR

Has anyone else noticed this? Right from their help files they state:

If you specify TColor as a specific 4-byte hexadecimal number
instead of using the constants defined in the Graphics unit,
the low three bytes represent RGB color intensities for
*blue*, *green*, and *red*, respectively.

Wow, anyone know of a particular reason for this. I'm working on an HTML
Table Editor and I had to swap the upper and lower byte to get the colors I
recognized. Threw me for a loop temporarilly. It wasn't until I read this
part of the help file the millionth time when their usage of the term
"respectively" hit me in the face. Doh.

Just wondering. Thanks,

Noticed it already a long time ago (about a year ago), but it also
took me some time to find out when programming a unit to read TARGA
files...
