Anyway, here is my suggestion:
Here is my approach:
1. Open all color equipped effects and change the color
2. Save the changes and overwrite the specific item file.
3. Start a second instance of Near Infinity in parallel and open the "Creature Animation Browser". Choose e.g. put the armor in "Armor Slot" and press "Apply".
4. If not happy with the result, change the color and save again.
5. Switch to the second NI instance and press F5 and open the "Creature Animation Browser". Choose e.g. put the armor in "Armor Slot" and press "Apply".
6. Repeat 4. and 5. until satisfied with the result.
Thank you vey much for reading this comment.
