Attached is a 'psioline' colored armor, which could make your psi armor distinguishable from the vanilla armor.
Edit:
If someone wants to use the armor, the sprite table don't need to be divided. In the 'extraSprites' section of your ruleset you can load it with:
- type: XCOM_9.PCK
width: 1024
height: 360
subX: 32
subY: 40
files:
0: Resources/.../personalArmor.png
Then it is automatically divided into sub-pictures.
