I wear Mossy Oak Breakup for one reason, it has plenty of black in it. This caught my attention after watching some videotape my dad and I took on a couple of days during the season. The days just happened to be overcast and rainy. Dad had on his Realtree camo and so did I. Being it was overcast, the timber had a darker hue to it than normal. Well the brown and tan stood out like a SORE THUMB in the video tape because it did not darken with the weather, not enough black in it. What we thought was a good camo set up with sapplings in front of us wasn't nearly as good as we thought once we watched the video. All camo will work on bright days, but I would highly recommend some sort of pattern with lots of black and darker colors. Try this little experiment on a cloudy day sometime out scouting for toms. Put a Mossy Oak or a camo with lots of black in it, and a camo with lots of tan and brown about 50 yards into the timber and stand back and look at it. You will see what I mean
