THe problem is REFRACTTINT. Using REFRACTTINTTEXTURE fixes this issue, for reasons unknown to me.
Ok, my forcefield texture refracts, and is coloured how I want it, however! It seems to magnify the amount of light on ANYTHING seen thru it exponentially

If you notice the wall, it is bathed in shadow, but thru the refraction texture, it is bright and clear. AND, any mildly bright areas are brightened beyond recognition. Can anyone help? Below is my .vmt code.
"Refract"
{
"$normalmap" "dvlstx/forcefield_normal"
"$surfaceprop" "glass"
"$bluramount" "1"
"$refractamount" ".100"
"$scale" "[1 1]"
"$envmap" "env_cubemap"
"$envmaptint" "[.3 .3 .3]"
"$REFRACTTINT" "[44 88 201 100]"
}
