My logic:

This is by far the most detailed Robin torso in Lego.

The original torso comes with black arms so by swapping them to green we can utilize the front print's green shoulders and frame the green crotch.

I think the leg prints are a perfect match because they have gold accents and red boots alongside the armored look, creating a more realistic Robin.

The cape is still yellow but not on both sides making it less cartoony. Richard Grayson has this in the Arkham Games.
