Is there an enbseries.ini setting aside from ambient light to restore the color to textures when they are illuminated by adaption or various forms of indirect lighting? Having the textures be lit up while in grayscale from having been within shadows gives it a photo-negative kind of appearance.

I know that having excessive ambient light will bring the colors back, but I'd prefer not to do this.

Better post sample images what you want to achieve, i don't understand half of that.

My goal is to make indirect light still allow some illumination, like in real-life, which both of these settings seem to accomplish. Unfortunately, all of the color is washed away during the shading/shadow process and thus the illumination is grayscale instead of having the color of the original textures.

The only way I've found around this is to set ambient light to 30% or higher (which then allows color), but would prefer a more realistic indirect lighting method instead of just pumping up ambient light.

Ambient and skylighting are tied together, you can't do anything to make image brighter, except changing tonemapping curves (which is real life like) and intensity of image. Colors computed like this:
result=albedo * ((GameDirectLighting*shadow + GamePointLighting*PointLightshadows) + (GameAmbient*skylighting*ssao*) + ssil) + specular;
So, you need to tweak intensities to much higher and modify properties of enbeffect.fx to get real life like result. Check hdr images (not fake shit called hdr), how they look in linear space.
