CS_TBL, it comes closer, but it is not what i ment.
Let me try and explain it another time, but written:
Purple is made out of red and blue.
Yellow out of red and green.
So if i want to make this purple ball yellow, i substract blue, and add green.
What i dont want is have this done pre-computed, as i changed it realtime.
Basicly, i ill use it for effects such as:
Nightfall
Sunrise
Drakredish looking caves
Brightblueish looking water
etc....
The SetColor function, only takes the light & darkness, and forces all colors to turn red.
What i need is (as shown in the picture)

Is a function that ADDS or SUBSTRACTS blue, or red, or green, or both TO and FROM an area on the screen, in real-time.
In addition i would like to know if it is possible to ADD and SUBSTRACT anything at all?
Like, if i where on top of the colorization to add a darker layer or effect, like a vail, that only lights up when i have a torch. (which i then would want to have a yellowish looking radius but not make ALL look pure yellow, just by adding a bit green and red for that zone.)
What i expect, is that i have to render the whole backbuffer, lock it, apply the effects, unlock it, draw the HUD (which will not be effected) and FLIP it.
Thank you.
