Apply color cast to video

I'd like to apply a color cast to a video, somewhat like the following (which I did on a still in an image editing program). Is there a way that I can do this in Avisynth? I've tried messing around with hue and saturation in Tweak() but nothing looks right. Any suggestions on what I might try? TIA

I have a VirtualDub filter that will do it:

You could import it into Avisynth.

aaahhh... Tint... why couldn't I think of that word? Thanks Don, your tip worked great.

In doing a search on how to import VD filters into Avisynth, I also stumbled upon a Tint() script. Playing with both now to get the look I am after.

Again, thanks much.

JFTR - another option would be using ffavisynth; you can use just about any filter that's in ffdshow in AviSynth, which includes the "Colorize" setting of the "Picture properties" filter...

ok, had to think of some else, besides work:
Code:
imagesource("white car.jpg",0,100,25)
crop(0,0,460,256)
converttoyv12()
greyscale()
vid = last
vid_r= vid.reduceby2()
v_mask = overlay(vid_r,invert(vid_r),mode="darken")
u_mask = overlay(vid_r,invert(vid_r),mode="lighten")
y=vid.coloryuv(cont_y=-80,off_y=-30,gamma_y=-60)
u=u_mask.coloryuv(cont_y=-200,off_y=-20)
v=v_mask.coloryuv(cont_y=-100,off_y=70)
ytouv(u,v,y)  
#histogram("levels")

stackvertical(imagesource("white car red.jpg",0,100,25).crop(0,0,460,256).converttoyv12())
Overlay could be replaceable by masktools, if you are pressed for speed.

Now that I have looked at the attachments, it looks like more of a "colorize" application. Tint overlays a color but doesn't totally kill the source colors. Colorize maps all colors to a single color (like a sepia photo). I just wanted to mention that in case the OP really was looking for a colorize effect. I have a VirtualDub colorize filter as well:

I did notice this. It wasn't originally what I was after, but I like the look of it in some of the video I was playing with. I will also give Colorize a try.
