The single reference for how OAK looks, sounds and feels — built so designers and AI tools produce work that is unmistakably ours. Colours, type, voice, commerce patterns and the vibe, in one place.

Who we are

It's not your age. It's your fuel.

OAK is a direct-to-consumer longevity brand. Our hero product is a single-serve creatine stick — a clinical 10g dose, 100% pure, natural lemon — positioned not as gym supplementation but as healthy aging: brain function and strength for people over 50.

The story is a battery metaphor. Creatine restores the cellular ATP your brain and body run on. We speak to capability, not decline — hopeful, specific, backed by research. Never fear-based.

The world is calm, editorial and apothecary-like: deep forest green, warm parchment cream, a refined serif wordmark, botanical imagery and thin line icons. One warm accent — gold — earns its place on ratings and highlights.

01 — Logo

The wordmark is the only mark

OAK green wordmark
OAK cream wordmark

Green wordmark on cream and light surfaces. Cream wordmark on green and dark surfaces.

Keep clear space of at least the cap-height around it. Never recolour, stretch, add effects, or place on a busy photo without a solid panel behind it.

There is no separate symbol or icon. Set in Passenger Display — the wordmark carries the entire brand personality.

Logo files — ready to use

The exact wordmark files in daily use. The logo green is #2E4F3D (brand green) and the cream is #EBE7D7 (Cream 100). Use transparent versions on photography, the solid-background versions where you need a guaranteed contrast panel.

The oak leaf

The hand-painted oak branch printed on the product box — our botanical signature. Use it sparingly as a quiet accent inside green fields or on cream; never recoloured, never busy. It reinforces the apothecary, natural-longevity world.

02 — Colour

A warm, monochromatic green world — plus one gold accent

Green-on-cream and cream-on-green are the two contrast modes. No gradients. Gold is the only accent, reserved for ratings and highlights.

A deliberate accent — not every heading. Reserve for the wordmark, large stat numerals and the occasional editorial hero line.

Open Sans — body copy 17–19px · line-height 1.6

One stick a day. A clinical 10g dose of creatine to support brain function and muscle strength — in a 100% natural lemon flavour. Set deliberately large for a 50+ audience, so it stays effortless to read.

05 — Photography

Warm, natural-light still life

Two registers, both valid. Brand photography is warm, natural-light still life — controlled, editorial, cream and neutral surfaces. UGC is real customers in real homes: honest, unstyled, trust-building. Never cold, never high-saturation, never gradients.

Ideal customer — hero

She is who we make it for.

Hero review · our current ideal customer

“I am 67 and I had started to think the brain fog was just something I had to accept. I was wrong. My word recall is sharper, I feel more present in conversations, and I am not writing everything down anymore because I actually remember things. My daughter noticed before I mentioned it to her.”

Iconography

Thin, single-weight line icons (~1.5px), rounded, outline, monochrome. Always in a circular hairline outline for benefit blocks. Lucide is the stand-in until OAK's own SVGs land. No emoji.

Motion

Quiet and functional. Short durations (140 / 240 / 420ms), ease-out. Fades and gentle height/opacity. The scarcity dot pulses softly. No bounce, no spring, no decorative loops.

Layout & cards

4px scale, generous 64–96px section padding, 1200px max (720px reading width). Radii 6 / 10 / 16 / 24, pills 999. Low warm diffuse shadow, 1px hairline border. No harsh shadows, no coloured-left-border cards.
