Undertone isn't complicated. It's just been explained backwards.

If you've ever taken a color quiz and felt like the result was... close, but not quite you — or taken two different quizzes and gotten two different answers — you're not bad at this. The tests were probably the problem.

Undertone is the foundation everything else gets built on. Get it right, and your whole color season clicks into place. Get it slightly off, and everything built on top of it feels just a little bit off too — like a sweater that's almost your size.

This free guide walks you through what undertone actually is (and the thing most explanations get backwards), why the popular tests keep leading people astray, and a simple method you can do at home, with stuff you already own, in about five minutes.

IN THE GUIDE:

• What undertone actually means — and how it's different from overtone (yes, most explanations have this flipped)

• Why the classic tests get it wrong so often (the jewelry test has a lot to answer for)

• A quick, reliable method you can do right now, with what's already in your closet

• Where undertone fits into the bigger picture of finding your full color season

It's short, it's free, and it's the first thing I wish someone had handed me before I went down this rabbit hole myself.
