I went with red, as I've had red, green and blue and red is the best IMHO. The whole "daylight visible" point is lost on me. Its not an Aimpoint or eotech and the bold circle is very fast (if you cant center it on your target you should set the rifle down and take up something else). If you run it on and cover a dark background its plenty visible, even here in sunny AZ.

If there was no advantage to bright daylight visible illumination for fast target acquisition, Aimpoints would come with just a black dot. But millions of units sold indicate that the market desires the daylight visible illumination, thus the reason other manufacturers are quickly working to put the technology in their products. </div></div>
A dot is very different than an extended reticle (like a duplex crosshair) to your eye and brain. A dot can be very fast, but requires illumination day and night if it's not part of a larger reticle design that can naturally draw your eye to the center. On the other hand, an extended reticle like the USO C2 doesn't require day-bright illumination, IMO. The design of the C2 brings your eye to the center. Nevertheless, a daylight-bright illuminated cross at the center of the C2 could make it slightly faster. One of my favorite reticles is the one in the ELCAN 1x/4x SpecterDR with a brightly lit dot at the center for daylight use and with the main crosshair-type reticle unlit. The lit dot and the unlit crosshair together bring your eye to the dot very quickly.
The USO DFP reticle concept would work well here, lighting only the center aimpoint (dot or cross) enough to be brightly visible in daylight.
