Well I found this on the titebond website:
What are the resulting colors when the Titebond Wood Glues dry?
Titebond III Ultimate – light brown
Titebond Original – yellow
Titebond II Premium – translucent yellow
Titebond Dark – brown
Titebond Liquid Hide – transparent amber
Titebond Melamine – colorless
Titebond No-Run, No-Drip – transparent with a light brown tint
Titebond Polyurethane – yellowish amber
Titebond Translucent – colorless
Titebond Instant Bond – colorless
Maybe you have one of the amber or brown ones and it's maybe a bit more amber or brown than usual for whatever reason
