Hey guys.....I just got off the website "Quality Deer Management Association".
This is what they expert says
On a lighter note, the second question asked about different coloration in antlers. Several factors may be responsible. According to Dr. Bubenik, antler color depends partly on the amount of oxidized blood on the antlers (from velvet shedding) and partly from a chemical reaction between the blood and juices from plants on which the antlers are rubbed. If a buck begins rubbing his antlers before the velvet and blood have completely dried, the blood stains the antler and gives it a darker color. The predominant species of trees in an area also influence the color. Pines allegedly cause darker antlers, likely from bucks rubbing on exposed sap after they break the tree's cambium layer. A buck's genetics may also influence color. Some bucks are predisposed to having lighter or darker antlers, and to rub more or fewer trees. A buck's age can play a role as older bucks tend to rub more than younger animals. Finally, the time of year can influence color as antlers generally lighten over time due to the bleaching effect of moisture, sunlight and extreme winter conditions.
Do individual bucks maintain a consistent color from year to year? According to Dr. Mickey Hellickson, chief wildlife biologist for the King Ranch in south Texas, yes, with a few exceptions. The antlers of some individual bucks gradually become darker as the buck increases in age, likely due to increased rubbing behaviors as his dominance standing improves. The above reasons explain why you may see light, medium or dark antlers throughout the whitetail's range.
