Neurotoxin
You mean the screen or the numbers counting down? I don't know the screen prop, but the numbers counting down is an entity, vgui_neurotoxin_countdown.

i've tried that, but i cant see teh numbers in the game 
I had that issue, sometimes you have to rotate the "vgui_neurotoxin_countdown" to see it, try rotating it 180 degrees.

I use dust fog, and make it do a console command. I think the command is "neurotoxin" or something.
The neurotoxin vent is an overlay I think. Or I could be mistaking that for something else.
Oh. You were busy back there. Well, I suppose we could just sit here and glare at each other until somebody drops dead. But I have a better idea. It's your old friend: Deadly Neurotoxin. If I were you, I would take a deep breath. And hold it.
Not in wrath
The REAPER came today
An angle visited this grey path
And took the cube away

Anyway, the countdown the vgui, as for the monitor that's just a prop. The vent is a texture overlay. And the neurotoxin spray is "info_particle_system."

ok, good. I'm almost done. Last, I just need to know what to put into the color correction. Like, the lookup table, script think function, etc. Anybody know what to do?
Do you mean the neurotoxin color? If you do, then type "Human_cleanser_cheap" in the "Particle System Name" for "info_particle_system."
If you meant the screen turning into a different color, then I have no clue.
