background screen color

Is it possible to get background colors other than those shown in Settings?
I would like autocad color 111.

Thanks

This may help:

;|sub-routines to change Model Space & text window background & text
color(s). Autocad colors 1 - 7 are supported, any other
number, or nil, will go to black. Other colors can be added,
just make sure to convert from Autocad color to
OLE_COLOR number first. May need to adjust
text color as well.

To Kerry Brown,
Thanks for taking the time to answer. I was not specific enough. I meant the color form the true color tab, RGB color 111,111,111.

Thanks,
Tom

So is this the color you are looking for?
(vla-put-GraphicsWinModelBackgrndColor (vla-get-display (vla-get-Preferences (vlax-get-acad-object))) 7303023)

@Charles Alan Butler:
In my test the code in your last contribution does not work as intended. The color does change, but not to the specified true color.

So it appears that BricsCAD will not be forced into True Color background only Index colors.

An easier solution, if it's about changing background colours to another autocad color,

make a new button on a toolbar and in the command line box put in
$M=$(if,$(and,$(getvar,BKGCOLOR),256),BKGCOLOR;251,BKGCOLOR;256)

The above will toggle you between two colours, in this case 256 and 251
change either of those to 111 or whatever colour that suits your taste/needs.

Does Acad let you use anything else then the regular 256 colours these days ?

Yes, looks like it's been like that for a while. I wrote this LISP to toggle between Black and White quite a while ago and had to take this into account.

You could use VLE-rgb2aci to convert from rgb to the closest index colour

: (vle-rgb2aci 111 111 111)
8
: (vle-aci2rgb 8)
(128 128 128)
