No don't have to have color, just like if possible. Will DM.@Wolf4Ever with that small amount of light on scene is there a reason you want this in color ? Can you utilize another fixed cam with fixed aperture to cross cover the area for any color details you need ? With B&W on the PTZ you'll have more control and we can certainly balance out the 'bloom' you mentioned. Either way, if you want, DM me and we can set some time up for me to jump on your system, take a look and dial in to get this as good as possible for this FOV and location. Let me know
