What's the difference between canary (yellow) and white legal pads?

Canary yellow is the traditional legal-pad color and is the default across most picks here, including the Amazon Basics and Mintra pads; many writers find yellow reduces glare and visually separates notes from printed white documents. White pads like the TOPS 7533 and Ampad Gold Fibre white are preferred by people who scan or photocopy notes, or who simply dislike the yellow tint. Both perform identically for writing.
