DXF code for various colors

I am parsing DXF files and would like to know the colors associated with the numbers in the file. The DXF reference manual just states
Group code 62 means Color Number (fixed)
But I cannot find what the Color Number equates to.

Thanks in advance,

Look at COLORWH.dwg in the Sample folder.

Also, bear in mind that any entity whose color is "Bylayer" will not have a
Code 62 item in its association list. Only entities with an explicitly
assigned color other than Bylayer get an (assoc 62) value assigned.

While an entities color will not show up if it is bylayer, color 256 is bylayer.

 

Thanks for the responses to my question. Now that I know the color code visually, I am looking for the computer RGB values of those colors so that my program can parse the DXF and look the same color as in AutoCAD.

Thanks in advanced,
Koh

 

You can find functions to covert color types in:

C:\Program Files\AutoCAD 2005\Sample\VisualLISP

Color-util.lsp

Heres one I had wrote to convert TrueColor to RGB:

;9/23/04 Bill Zondlo
;TrueColor to RGB converter.
;OLEnum is the 0 - 16777215 True Color positive number.
;
;
(defun TrueColor-RGB (OLEnum / B G R)
(cond ((and (>= OLEnum 0)
(<= OLEnum 16777215))
(setq R (/ OLEnum (* 256 256))
G (- (/ OLEnum 256)(* 256 R))
B (rem OLEnum 256)
)
(list R G B)
)
(t (prompt "\nNumber not within range of TrueColor."))
) ;end cond.
)
