I've scoured the web and couldn't find an actual answer.  Just people posting on reddit and a several year old topic in the community about this, but the suggestions were "go to the setting and if it's not there contact support".  I spent some time with support and still didn't really get an answer.  

I have the newest model of the Floodlight Cam Pro.  It has the option for "Colored Night Vision" according to the site.  The support docs say to go to the 3 bar menu, select the device, device settings, video settings, and there should be an option to toggle that on/off.  However, this option does not exist.  I have installed the app on an iPhone, Android, and a Tablet.  Even checked on the web version(knew it wouldn't be here).  It is simply not an option like the support docs say.  

The support rep just stated, "It is only an option at night.  You can turn it off at night".  I didn't see that under video settings at night either.  Firmware and apps are all up to date.
