Shade
Stain types in plain words: surface, deep, and what mirrors exaggerate
Shade words are easier when you separate surface marks from deeper color change.
Surface marks
Coffee, tea, and tobacco marks are often discussed as surface stains. A hygienist may talk about polishing; that is clinical care, not a website diagnosis.
Deeper color
Some color change sits deeper in enamel or dentin. Educational guides list causes like aging or certain medicines without promising a DIY fix.
