All channels from explosia are exported by default (since C4DtoA 3.3.2), so you should be able to just read the color channel (e.g. in a standard_volume or volume_sample_rgb shader).

If it does not work, please send us a scene and I'll take a look.

Indeed, the Explosia FX integration is missing support for the color channel. I'm going to fix this in the next release. Meanwhile, if you need the fix right now, please request a custom build via support@arnoldrenderer.com.

Fixed in C4DtoA 3.3.7.1. You can now sample the color channel via the volume_sample_rgb shader.
