Terminator chaplain color scheme

Hello, I just bought a termi chaplain to join my terminator squad. I'm wondering if I could try to add some colours to make it pop a bit more in the unit while keeping black as the main colour.

I thought the "ribs section" of the torso could be a good candidate for a pinch of colour but I'm not too sure about the colour.

For now my guesses are around white, bone colour, gold or silver. Also maybe keeping the kneepad white.

What do you think about this idea ? Also if you did something similar I would love to see some pictures for inspiration
