Hi Jordan,
My suggestion to do so within knob_changed() was under the assumption that
you wanted to change the node's color dynamically (based on the selection
of certain parameters).
Also keep in mind that knob_changed() works the same way as in Python; it
will be called for any knobChanged event, so it's up to you to filter the
knob you're interested in. Otherwise it will be called for any knob you
change, or every time you move the node in the DAG, etc.
If you want to set a predefined tile color for your node, but allow the
user to change it afterwards, I think this would be best handled as a
knobDefault in your menu.py
Ex:
nuke.knobDefault('Your_node_class.tile_color', '0x00ffff00')
