If you have a cool undertone (Summer or Winter), hair colors without gold or orange warmth in them — ash, cool brunette, blue-black — tend to look the most natural, the same way golden or caramel tones can look brassy against cool skin.
Colors that work
Colors to approach carefully
These warm tones tend to look brassy or slightly orange against cool skin, fighting rather than complementing the undertone.
Summer vs. Winter hair
Both seasons are cool, but at different intensities. Summer suits softer, lighter cool tones — ash blonde or soft brunette. Winter suits deeper, higher-contrast cool tones — blue-black or cool dark brunette.
The undertone that decides your hair color decides your makeup too. Cool coloring generally takes plum and rosewood over warm bronze — though your eye color picks the accent. See eyeshadow colors that make your eye color stand out.
Frequently asked questions
What's the best blonde for cool undertones?
Ash or beige blonde, without golden or honey warmth in it. Golden or caramel blonde tones can look slightly brassy against cool skin.
Can someone with a cool undertone go copper or red?
A cool, muted auburn can work, but bright copper or orange-red tends to clash with cool undertones — a blue-based burgundy is usually a better red option.
