Brand guidelines
The working reference for how Exatom looks: logo, color, type, and the interface elements built from them. Every value here is the real brand value — copy it from this page, don't approximate. Presentations and social media build on it, in their own guides.
Logo
The mark is a rounded square holding the Exatom glyph, paired with the wordmark. Four lockups cover every background; the icon travels alone where space is tight.
Variants
Pick by background, not by preference. Full color is the default; monochrome exists for print and single-ink contexts.

On backgrounds
The logo must always sit on a flat brand color or a quiet area of a gradient — never on a busy image without a scrim.
Clear space & minimum size
Keep clear space equal to half the height of the icon on all four sides. Below 88px wide, drop the wordmark and use the icon alone.

Color
Five core colors carry the brand. The extended palette exists for highlights, illustration and campaign work — it supports the core, it never replaces it.
Core palette
Blue, Warm White and Dark are the primary brand colors across every application. Do not substitute unapproved alternatives.

Neutrals
A five-step scale from the brand dark. Use it for text hierarchy, dividers and disabled states — not as a second brand color.

Extended palette
Highlights, accents and marketing material only — always in balance with the core palette, and never as a replacement for it in primary brand applications. Mint is the loudest of the set; treat it as a spark, not a surface.
Gradients
The gradients carry the story, not just the surface: blue to mint is the before and after — friction resolved, conversion restored. Use them as backgrounds for depth, never behind body copy.
Pairings
Every approved mark-on-background combination, core palette first, extended palette below. The mark always inverts against its ground so it holds contrast down to 24px.
Text on color
Pairings carrying type, laid out as formats rather than text blocks: 400 tall, so the modular margin is 20px, the headline sits with its cap-height on the top margin, and the bottom margin carries the description and action on the left with the mark on the right. The ink is always the lightest or darkest member of its own pair, never the accent. Blue Light and Dark lead because they are the core palette; the four extended pairings below them are campaign work.

Mesh gradients built the same way as Color's three flat ones — several radial blobs blended over a solid backdrop, plus a grain pass. Four blue, working closest to the core palette; two each for Mint and Coral.
Typography
Instrument Sans carries every headline, subhead and button. Inter carries everything you read at length. Two families, no exceptions.
Families
Both load from Google Fonts. Do not substitute other faces in brand communication.
Instrument Sans
Display, headlines, subheads, buttons. Tight tracking at large sizes gives the brand its confident, compact voice.
ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz
1234567890 !@£$%^&*()
Inter
Body copy, captions, interface text, data. Chosen for legibility at small sizes and in dense tables.
ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz
1234567890 !@£$%^&*()
Weights
SemiBold is the heaviest weight the brand uses — never Bold or Black, in any family. Medium carries most applications, Regular the smaller body copy.

Type scale
Headlines are 4× the body size with tighter tracking. Subheads and buttons are 2×. As type size increases, tracking tightens.
Boost conversions
See where visitors drop off
Exatom captures every interaction, flags friction points, and recovers drop-offs before they're lost — field by field, not just page by page.
Field-level metrics update within 72 hours of the tag going live. No cookie banner required.
Line-height
Larger type takes tighter line-height; smaller type needs more room to read. Headings sit between 110–120%, body copy around 140%.
100% — too tight
If you want to boost conversions, then Exatom is the place to do it.
120% — headings

Foundations
The measurements underneath everything else: how far things sit apart, how sharp their corners are, and where a line is allowed to appear.
Spacing
A 4px base unit, stepping up in the values below. Everything — padding, gaps, section rhythm — is a multiple from this scale. Nothing sits on an off-scale number.
Corner radius
Two extremes and little in between: controls are fully pilled, surfaces are close to square. That contrast is what makes a button read as a button.
Borders & elevation
Separation comes from hairlines, not shadows. One border colour, one weight, everywhere.
Layout
UI elements
The building blocks the website is assembled from. Radii, weights and colors here are the defaults — deviate only with reason.
Buttons
One primary action per view, repeated down the page rather than competing with alternatives beside it. Blue is the only filled action colour; Dark is reserved for a second, quieter primary on light sections.
Primary, Secondary, Dark, Tertiary, Disabled, each at both sizes. Tertiary is text alone — no fill, no border, no arrow. It carries the third-most-important action on a view, and never the only one. On hover the label drops out of the bottom while a second copy arrives from above, clipped by the pill — one 420ms move. Nothing else changes: fill, border and text colour hold, so the roll is the whole of the feedback. Tertiary is the exception — with no fill to clip against it underlines instead. Disabled does not respond at all, and neither does anything when the visitor asks for reduced motion.
On dark
On Dark #18122D the roles stay the same but the colours invert. Blue is not usable as a fill here: at 2.6:1 against this ground it fails contrast, so the primary action becomes white and Tertiary switches to Blue Light.
Cards & metrics
Result figures are the proof this brand runs on, so they are set as a layout, not as a text block: the frame is 420 tall, giving a 17px modular margin, the figure sits with its cap-height on the top margin, the label runs at a quarter of the figure size along the bottom margin, and the mark closes the card bottom-right at twice the margin.

Labels
Small, quiet, and never more than one accent colour in a single group. Labels are tags, so they take the fully pilled radius.
Forms
States, field types, a form in full, and the rules we hold ourselves to.
Exatom sells form conversion, so our own forms are the shortest argument we have. Everything below is what we ask clients to do: labels above the field, one column, one question at a time, and error text that names the fix instead of the failure.
States
Six states, and every one of them says something. A field that looks identical whether it is empty, wrong or accepted is a field people abandon.
Default — placeholder shows the shape, never the label
Focus — 3px ring, border to Blue
Filled — border darkens to Gray 300
Add the domain ending, like .io or .com
Checked against the VIES register
Disabled — prefilled, so do not ask twice
Field types
Four beyond the text input. Radios and checkboxes are full-width targets, not 18px dots — on mobile the label is the tap area.
Chevron is drawn, not native, so it matches the icon set
Mark optional fields, never required ones — most fields are required
A form in full
The same rules assembled. One column, grouped by what the visitor is thinking about, and the address block does the lookup instead of asking for four fields. That single change is what moved Kia Germany.

Maastricht, Sint Servaasklooster 14 — found from the postcode, so street and city are never asked.
What we hold ourselves to
Drawn from the friction points we find in client forms week after week. If our own form breaks one of these, it is a bug.
DO
- Label above the field, always visible while typing.
- Validate when the field is left, not on every keystroke.
- Say what to do: “Add the domain ending”, not “Invalid input”.
- Derive what you can — address from postcode, company from email domain.
- One column. Two columns only for values that belong together, like postcode and number.
- Keep the submit button reachable without scrolling past the last field.
SKIP
- Placeholder text standing in for the label — it disappears exactly when it is needed.
- Asterisks on required fields when nearly everything is required. Mark the optional ones.
- Clearing what someone typed because the format was wrong.
- Asking twice for something you already have.
- A reset button next to submit.
- Error summaries at the top with no link down to the field.
Icons
Phosphor Regular, and nothing else. One weight, one grid, drawn on 256 so every glyph lines up at any size.
Exatom uses Phosphor for every icon, regular weight, on a 256 grid. It is the only icon library in the system — no Lucide, no Heroicons, no emoji standing in for an icon. Where a third-party component ships with a different set, swap it for the Phosphor equivalent. Below is the working set for the platform's features, with the Phosphor name each one maps to.
Team
The official set of headshots and bios — for LinkedIn, the about page, speaker bios, press. One row per person, one crop, one background. Next to each photo is the person's line drawing, the illustrated version for decks and visuals.
