Hey Wayne, my blender does not have that color option to make determinations of my bones being active etc. What is the addon for that?
Hi Yisrah YYAbrahaim ,
That's not an Addon, but in newer Blender Versions, they are hidden, click on the symbol/down arrow and you get the option to choose from a preset, or add custom colors:
In 3.5 or earlier, make sure you add a Bone Group (Pose Mode):
Then you get the color options.
