Final Fantasy XVI [Mod Request] - Climb Points Color Change

[Arothgar]

So no clue how to mod myself, so asking someone else with the know how.
If its possible, may not be, but could we get the climbing points that are a glaring yellow change to a more natural color.
Its quite jarring when in Mt Nibel youre climbing and the natural rocks are marked yellow, or in Kalm same thing.
So if anyone is a wiz at these sorts of things, please make a mod to change the climb points color.
