Cool undertones look best in lipstick with a pink or blue pull: berry, rose, blue-based red, plum, raspberry, and muted mauve. Avoid orange, brick, warm coral, and brown-based shades — they fight cool skin and pull it grey. Within the cool family, Summers wear soft muted versions; Winters go vivid and high-contrast.
Lip color flatters when it echoes the undertone already in your skin. Cool undertones carry a pink, rose, or bluish cast beneath the surface, so lip shades in the same family create harmony — the lip and skin read as one polished whole rather than clashing. The specific families that work:
The blue-red rule. When buying a red lipstick, look for it described as "true red," "cherry," "blue-red," or "cool red." Avoid "tomato," "fire engine," "warm red," or "brick" — those signal orange pull that will age cool skin.
Orange-based lip colors contain yellow pigment that fights the pink-blue cast of cool undertones. The result is that the lip color draws out any grey or sallow quality in the skin rather than the natural flush.
| Shade family | Why it clashes | Cool alternative |
|---|---|---|
| Warm coral / orange-coral | Yellow-orange base vs. pink undertone | Pink-coral or rose |
| Brick red / terracotta | Brown-orange pull amplifies grey tones | Blue-based red or plum |
| Warm nude / caramel | Yellow-beige casts skin ashy | Cool mauve or dusty rose nude |
| Peach | Strong yellow-orange family | Soft pink or berry |
| Warm brown / cinnamon | Red-brown with orange undertone | Deep berry or cool burgundy |
All cool undertones share the same family of flattering hues, but the value (light vs. deep) and chroma (clear vs. muted) of the right shade shifts across the four cool seasons in the Sci·ART 12-season system.
Soft, muted, light. Dusty rose, powder pink, muted mauve. Avoid anything too vivid or dark — it overwhelms a Light Summer's low-contrast palette. Think "just-bitten rose" over "bold plum."
Muted, medium depth. Soft berry, muted raspberry, rose-mauve. True Summer can go a shade deeper than Light Summer but stays in the blended, never-bright zone.
Clear and deep. True red, vivid berry, deep plum, bright raspberry. True Winters can wear the classic blue-red at full intensity — bold is the point.
High-contrast and vivid. Bright cherry-red, fuchsia-berry, vivid raspberry. Bright Winters need saturation; a muted rose reads flat and washed-out on them.
Not sure which cool season you are? Summer seasons are defined by muted, soft chroma; Winter seasons by high-contrast, clear chroma. Both share the cool undertone axis but differ on brightness. Tonebook identifies all three axes — undertone, value, and chroma — from a single selfie and places you in the right season.
The lip family stays the same; the intensity shifts with the occasion.
| Look | Summer seasons | Winter seasons |
|---|---|---|
| Everyday / natural | Cool mauve, dusty rose balm, sheer pink | Cool nude-mauve, sheer berry |
| Work / polished | Soft rose, muted berry, cool pink-nude | True red (matte), berry, deep rose |
| Evening / bold | Deep berry, plum (avoid going too dark) | Deep plum, vivid raspberry, classic blue-red |
Knowing you are "cool" is a start, but the right level of depth and chroma in a lip color depends on your specific season. Tonebook analyzes one selfie across all three axes — undertone, value, and chroma — using direct pixel sampling with lighting correction. It places you in one of the 12 Sci·ART seasons and builds a curated color palette, including makeup shades suited to your exact combination. The first analysis is free, and it reads accurately across Fitzpatrick I–VI.
One selfie places you in the 12-season system — including which berry, rose, or red is right for your specific season. Free first analysis, inclusive across all skin tones.

Cool nudes should lean pink-beige or mauve, never peachy or caramel. Look for descriptors like 'dusty rose', 'cool taupe', or 'muted berry'. A warm-peach nude pulls orange against cool skin and creates a washed-out effect.
Both are cool, but Summer is muted and soft while Winter is high-contrast and clear. Light Summer suits dusty rose, soft berry, and muted plum. True Winter suits vivid raspberry, deep burgundy, and pure blue-red.
Orange-based corals clash with cool undertones. However, a pink-coral (pink-leaning coral with no orange cast) can work for Light Summer and True Summer in a daytime look. When in doubt, test the color against your bare wrist veins — if the coral reads more pink than orange next to your blue-purple veins, it may work.
The most reliable home test: hold silver then gold jewelry beside your bare face. If silver makes your skin look clearer and healthier, you are cool. Blue or purple wrist veins also signal cool. Tonebook confirms undertone from a single selfie with direct pixel analysis, removing guesswork.
