Borrowed chords come from the parallel key - the major or minor scale that shares the same root. In C major, you can borrow chords from C minor. They're not "wrong" - they're intentional.
The borrowed chord keeps the original tonic but changes one or more scale degrees. Used briefly, that contrast can mark a transition or give a repeated progression a new point of focus.
How borrowing works
In a major key, chords from the parallel minor can be used for contrast. Common choices include the following chords, although the best choice depends on the melody and the chord before and after it:

bVI - Ab major vs diatonic vi - A minor
iv - F minor vs diatonic IV - F major
Where you hear them
Borrowed chords are everywhere once you know what to listen for:
- - bVII - Rock, pop, EDM. Gives a powerful, modal lift.
- - bVI - Film scores, epic moments. Think Hans Zimmer.
- - iv - Bittersweet moments. "Creep" by Radiohead uses IV -> iv.
- - bIII - Psychedelic, dreamy. Common in classic rock.

Why borrowed chords matter
Diatonic chords give you a solid foundation, but they can start to feel predictable. Borrowed chords let you break the rules deliberately - adding surprise and emotional depth without leaving the key entirely.
Key takeaway
Borrowed chords come from the parallel key (same root, opposite mode). Common examples include bVII, bVI, bIII, and iv. They add chromatic colour while still retaining a relationship to the parallel key.
Next: secondary dominants - borrowing the V -> I pull and pointing it at any chord in the key for extra tension.
Try it
Pick one pair, such as IV and iv. Before playing, predict which note changes when the chord is borrowed from the parallel minor. Play both versions and name the change: F major to F minor lowers A to Ab.
Now place the borrowed chord after C major in a four-chord loop. Decide whether it works best as a brief colour or as the emotional centre of the loop.
