GSWEAR Posted July 5, 2011 Share Posted July 5, 2011 Green for me, I am moderately color blind with reds and they don't show up well. My 1911's, M&P's and revolvers that I shoot in IDPA all have green FO's. Greg Link to comment Share on other sites More sharing options...
RePete Posted July 8, 2011 Share Posted July 8, 2011 I run green. I see it faster than red. Some people are going from green to red because of the foliage on the berms, but I think flourescent green is a differnt green than foliage. Link to comment Share on other sites More sharing options...

redmanfixit Posted July 8, 2011 Share Posted July 8, 2011 The sun has a lot of iron and sodium in it. At atomic temperatures, those elements emit strong yellow (sodium) and green (iron) light. the photopic vision curve ( the sensitivity curve of the human retina in daylight) peaks it's sensitivity at the highest level of output of the solar luminosity curve or more correctly, emission curve. (Interesting correlation) Humans do generally see best in the boundary area between those two colors, given that the lens system in your eye is not far or near sighted. Also, as we age, there is a protective yellowing of the crystalline lens in the eye and there can be clouding also for a variety of reasons. These effects may effect the preference you show as regards color. Tinted lenses can interfere with the sharpness of your vision, especially very dark lenses, due to aperture effect. This is huge for older shooters that are afflicted with presbyopia and experience compressed depth of field anyway. More light = smaller pupil = sharper sights. Lenses that block wavelengths from 400nm to about 410nm or 420nm (near blue range) will give sharper vision also. Blue photons have very high energy and will overstimulate photo receptors of all kinds. Think of it as optical noise. It is VERY important that you be certain whatever lenses you wear, ESPECIALLY if tinted darkly, absorb or reject UV range wavelengths. (below 400nm) If anyone would like an explanation in greater detail of the optical physics of this, I'd be happy to stupefy you with boredom as regards why all the above is true. If you must wear tinted lenses, a light grey or neutral density will give you the best color rendition. If you can get a fiber for the front sight, in any color that has UV sensitive phosphors added to it, it will fluoresce in daylight and especially in cloudy or early morning/late evening light conditions. (lots of UV around) So the sights will be VERY visible in comparison to materials that do not have this "doping". It's easy to see on a cloudy day or under a "black light". These are the physics and of course they do not account for "human preference". If you test it though, you'll find that equipment which matches these criteria, allows you to get on your front sight faster. Brian mentioned in his book, that he didn't like yellow so much as it seems too bright, as I recall. There are variables as regards individual retinal sensitivity, when you introduce the fact that 78% or so of males have a red green color deficiency. Your results may vary.

DonovanM Posted July 9, 2011 Share Posted July 9, 2011 I've tried both. Didn't make a damn bit of difference. Ended up with red, works fine. If you don't pay attention to the front sight consistently, that's a software issue, not one best solved by switching out colors every other match.

Gatekeeper Posted July 9, 2011 Share Posted July 9, 2011 Bright red fibers tend to "bloom" on me and look like a fuzzy blob to the point I have trouble making out the top of the sight. I have to darken the fiber with a sharpie to allow less light and dim the dot almost to the point that I'd be just as well off without a fiber at all. A bright green fiber on the other hand is a perfectly crisp and clear, draws my eye quickly to the front sight and allows me to still see the top of the sight crisp and clear. Must be something with my eyes. Have been using fibers on pistol sights for less than a year but I noticed the same thing almost 20 years ago when I started shooting fibers on my bow sight. Green and yellow were perfect, red was fuzzy Link to comment Share on other sites More sharing options...
CDPMatt Posted July 9, 2011 Share Posted July 9, 2011 Green. But for a different reason than most. After shooting OPEN for years, I tend to treat a Red FO Front Sight like a dot and completely ignore the rear sight. Yep, same here.... Link to comment Share on other sites More sharing options...

lucky #7 Posted July 10, 2011 Share Posted July 10, 2011 I prefer red. Green is too bright to my eyes. I guess it transfers too much light. A green fiber rod turns into a huge glowing star of light that washes out everything around it including the target and the rear sight notch. However, the red fiber optic is just bright enough to provide heightened awareness of the front sight. Red remains a crisp dot, while the green glows like a star shaped reflection.

rooster Posted July 10, 2011 Share Posted July 10, 2011 I took red green yellow and gold fibers out in the sun and put them in my hand arms lenght out closed my eyes then opened them and whichever one stood out thats what I used, for me it was red.

T_Linville Posted July 12, 2011 Share Posted July 12, 2011 ok i may be weird but yellow has worked the best for me. I have tried green and red, green would be my second choice, like somone else said red just looked a little fuzzy to me. Link to comment Share on other sites More sharing options...
sfinney Posted July 12, 2011 Share Posted July 12, 2011 The Brightest color is not always the best. You need just enough attention to your front sight so you don't forget its there, but not enough to flare and blur your front sight picture. Green (and sometimes pale yellow) work best for ME in that regard, red just "blooms" to much. Each to his own. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted July 12, 2011 Share Posted July 12, 2011 Hello: Take a look at a traffic light and see which colour you see better from a distance. Green for me, besides green means GO Learned that little trick from Benny Hill Thanks, Eric Link to comment Share on other sites More sharing options...
cas Posted July 13, 2011 Share Posted July 13, 2011 Green for me, I am moderately color blind with reds and they don't show up well. A fiber optic front sight with no fiber optic in it works better for me than red. They might as well not be there because I can't see it. My fiber optics are yellow. At least I thought they were till someone told me they were green. They could be lying. I wouldn't know. Link to comment Share on other sites More sharing options...

Aggieddad02 Posted August 31, 2011 Share Posted August 31, 2011 Red works best for me. Got my M&P 40 Pro and looked at the green but it just did not stand out enough that I could pick up the front sight quickly. Link to comment Share on other sites More sharing options...

Palmetto Sharpshooter Posted August 31, 2011 Share Posted August 31, 2011 Did some research: Physiology of color perception http://en.m.wikipedia.org/wiki/Color_vision Of the three cones in the human eye green is picked up by all 3. Where red is seen by 2 Also red makes your heartbeat faster where green is calming Then why isn't there a blue F/O? Blue is calming too. Link to comment Share on other sites More sharing options...
CZinSC Posted August 31, 2011 Share Posted August 31, 2011 My gun has a front sight? When I remember to focus on it, the green shows up better for me. I used Red until a few months ago when I switched over. Link to comment Share on other sites More sharing options...

Dwain C. Baer Posted August 31, 2011 Share Posted August 31, 2011 (edited) I have heard very good comments regarding the green fiber optic over the red color. During the next change, I'll use the green and see if it really is an improvement over the red... Edited August 31, 2011 by Dwain C. Baer Link to comment Share on other sites More sharing options...

Dwain C. Baer Posted August 31, 2011 Share Posted August 31, 2011 (edited) I run green for sports centered around shooting cardboard and red when shooting steel challenge. Those combos seem to stand out the best for my eyes. A few weeks ago, I had problems focusing on my red fiber optic while shooting red pepper poppers. Thought the green might be better in those situations Edited August 31, 2011 by Dwain C. Baer Link to comment Share on other sites More sharing options...
