I don't think yellow text that you can throw away, change to pink, and is mentioned to should be turned some shade green, is convincing evidence.

Yellow text is also used by Papyrus for the barrier and when he refets to Asgore, who is usually named in red, and the ball game confirms yellow to be Justice.

So, while the red soul may be Fate, or pretty much anything else that isn't covered, yellow shouldn't be Determination.
