Is it possile to change the color/shape of the crosshairs for all
weapons (AK-47, MP4, Desert Eagle, etc.) in the game counter strike (v
1.5)?  If so, how do I do it?  If there are sites where I can download
new crosshairs, please provide links and if the site does not have
instructions on how to do it, please provide them.  Please do not
answer this unless you are certain that your answer will work. 
Thanks!

Hello, Phantazem,
I looked around the Net and saw a cheat command you can use to change
the crosshair color. I think though it's a command set before starting
a scenario.

I will quote the instruction: 'Enter the console on the server machine
and enter "sv_cheats 1". Then, change maps by typing "changelevel
dust" (or any other map). Finally, enter one of the following codes at
the console...'

--> adjust crosshair or adjust_crosshair

This is the command for changing the color of the crosshair.

I hope this has helped you enjoy the game better! Make a request for
clarification if you find any problem with my answer. Thank you.

It works!  Thanks!

you do not need to click in the sv_cheats1 command this is for
adjusting cvars and server commands, just simply press '`'(default
console command) and type in adjust_crosshair and it will change
color.

Or you could have just used the GUI (pressing shift by default) and
went changed the crosshair color from there.

moreover, you are able to change zoom crosshairs (ex: when you zoom in
with the AWP and get a new crosshair). A simple search on the Internet
will get you access to custom crosshairs or a tutorial on how to make
your own.
