# Marrow brand guidelines

One page. The locked rules.

## Color palette

Four tokens. No additions, no off brand variants.

| Token       | Hex      | Use                                                                     |
| ----------- | -------- | ----------------------------------------------------------------------- |
| Oxblood     | #6B0F1A  | Primary accent. CTAs, eyebrows, highlights, brand mark fill.            |
| Bone white  | #FBF8F2  | Primary background on light surfaces. Foreground text on dark surfaces. |
| Bone cream  | #EFE9DC  | Secondary background. Inputs, alternating section blocks.               |
| Black       | #0A0908  | Primary text on light surfaces. Foreground on the dark trust strip.     |

The oxblood is canonical. We do not run a brighter red, a darker red, or a desaturated rose. If a surface needs more contrast, use bone cream against bone white instead of shifting the red.

## Typography

| Family             | Weights used                | Use                                                         |
| ------------------ | --------------------------- | ----------------------------------------------------------- |
| Switzer            | Extrabold (800)             | Display headlines, section titles, hero copy.               |
| Inter              | 300, 400, 500, 600, 700, 800 | Body, lede, navigation, buttons, form labels and inputs.    |
| Cormorant Garamond | Italic 300, 400             | Editorial accents, pull quotes, italicized spans in heads.  |
| JetBrains Mono     | 400, 500                    | Eyebrows, labels, numerals, technical micro copy.           |

Line height stays generous on body copy (1.6 to 1.75). Letter spacing is negative on display sizes and positive on mono labels.

## Logo

The mark is a hex grid inside a circle with a filled oxblood center hex. The wordmark sets "Marrow" in Switzer Extrabold to the right of the mark.

### Clear space

Keep clear space equal to one full mark height on every side. Nothing crops into that boundary.

### Minimum sizes

Mark only: 32px on screen, 12mm in print. Wordmark lockup: 96px on screen, 24mm in print.

### Color variants

| Variant                          | When to use                                          |
| -------------------------------- | ---------------------------------------------------- |
| Bone white mark on transparent   | Dark surfaces. Black background, oxblood background. |
| Black mark on transparent        | Bone white and bone cream surfaces.                  |
| Wordmark on white                | Documents, slide decks, signatures.                  |
| Wordmark on black                | Dark slide decks, app splash, video lower thirds.    |

## Logo do

- Use the bone white mark on dark surfaces.
- Use the black mark on bone white or bone cream surfaces.
- Preserve clear space of at least the mark height on every side.
- Scale proportionally. SVG is the default delivery format.

## Logo do not

- Do not stretch, squish, or rotate the mark.
- Do not recolor the mark or apply gradients.
- Do not add drop shadows, glows, bevels, or other effects.
- Do not place the mark on busy photographic backgrounds without a flat plate.
- Do not redraw the mark or change the geometry.
- Do not pair the mark with another logo inside the clear space boundary.

## Photography style

Dark luxe. Heavy contrast. Cool shadows with the oxblood used as the only warm accent in the frame. Real coaching environments. Power racks, kettlebells, sled tracks, chalk. Daylight where possible, controlled studio where not.

What we do not use:

- No stock fitness imagery.
- No supplement aesthetics. No protein scoops, no bro-science gym signage.
- No gradient overlays on photos.
- No before-and-after composites. Marrow does not make body transformation claims.
- No medical or clinical environments. Marrow is software for coaches, not a clinical product.

## Voice

Plain. Hard rules above flair. No em dashes. No en dashes. No parenthetical hyphens. Sentences end with periods, lists with periods, prose with periods. Eyebrows in mono uppercase. Headlines in Switzer Extrabold. Body in Inter Regular.

When in doubt, write the sentence shorter.
