New rules that require youth to wear hunter orange when hunting take effect Aug. 1, 2011.
As of that date, hunters age 17 and under are required to wear a hunter (fluorescent) orange exterior garment or hat when hunting game mammals or upland game birds (except turkey) with any firearm.
Details of the regulation:
Archery, turkey and migratory bird hunters are exempt from the hunter orange requirement. (Turkey and waterfowl have excellent eyesight and wearing hunter orange could reduce hunter success.)
The Fish and Wildlife Commission adopted the new rule last year  to protect youth hunters from vision-related firearm incidents. Adult hunters are also strongly encouraged to wear hunter orange when in the field.
Some controlled (limited entry) youth elk hunting seasons open Aug. 1 and general season bear and cougar will also be open that day. But most hunting seasons don’t open until September or October.
