You perhaps need one of the blender guys, but there is in 
global_settings {} an option called ambient_light which you can set. 
Say, ambient_light color rgb <0.7,0,0> such that the all ambient colors
in a scene get multiplied by that value.

If you are not using radiosity and the emission finish components have 
the rgb sliders/settings you need, perhaps using emission over ambient 
and option.

You could also add a low intensity shadowless light of the color tint 
you want, but it would be applied to all surfaces. Everything would be 
tinted. Negative shadowless lights an option too which - depending - 
might give you better control.

Note ambient >0 is applied as an adder to the resultant color everywhere 
in much the way a shadowless light is. Meaning, you'll get a less 
visible tint in lit areas too with the ambient_light option. This can be 
compensated for somewhat by tweaking your normal light source colors.
