MentionX brand guidelines

01 · Mark

Logo and wordmark

Mention

Light backgrounds: the black solid diamond.

Mention

Dark backgrounds: the transparent glass diamond.

• The logo is always Mention + diamond. Never type “MentionX” as the logo and never put a plain red X beside it. The diamond is the X.
• The glass diamond is for dark backgrounds only. Never on pearl, white or photo backgrounds. There is no white or crystal diamond.
• Diamond width = 1.1 × the “Mention” font size, everywhere. Never resize either part alone.
• Wordmark: Sora 600, letter-spacing −0.05em. Silver gradient on dark, black-to-slate chrome on light.
• Never redraw the diamond. Use the files and pick the size by display width (64, 160, 400, 800), never upscale.
• Where the diamond sits inside a CTA, it has no circle or background: just the bare diamond.

02 · Colour

Three families: black, silver, red

Every gradient is sharp and shiny: a bright specular top band, a crisp mid-tone and a deeper base. No flat fills for brand elements.

• Red is the action colour. The X, the gap, a key number, a warning. It carries a gradient (#FF8A78 → #FF3B33 → #B0080F), never flat coral and never a background.
• Retired: gold, champagne, copper, coral, sky blue, navy, violet and teal accents. They do not appear on the site or in new creative.
• Exceptions: AI engine logos keep their own brand colours; green (#34D399 / #0E9F6E) means status only (completed, monitoring, saved); the dashboard mockup keeps its legacy accents until the app is restyled.

03 · Surfaces

Black and pearl, one continuous page

• Dark: pure black with long, slow silver-grey bands (about 1800px each, slightly angled). Moon at the real current phase in the top-right corner, faint silver stars and rare silver shooting stars.
• Light: pearl with a light-silver finish, never pure white. No moon, stars or blue wash. Shine comes from chrome headlines and the silver shaft in the hero.
• The page is one continuous surface. Sections never sit in boxes or change colour abruptly; colour changes are slow and natural.
• Cards and the nav are glass: frosted, with a hairline silver rim.

04 · Buttons

Primary CTA

Check my AI visibility

Light: metallic black, silver gradient rim and sheen, shiny silver label, transparent glass diamond.

Check my AI visibility

Dark: chrome silver, shiny black label, bare solid black diamond.

• The CTA is the inverse of its surface: black on pearl, silver on black. Red is not used for buttons.
• The diamond is the inverse of the button: glass on the black button, solid on the silver button.
• One primary CTA per view. Secondary buttons are plain glass with a silver hairline.

06 · Typography

Sora and Inter

• Headlines are chrome: silver chrome on dark (bright crown, silver body, one darker band), polished black chrome on light (black body with one bright reflective band).
• One word or number per headline may take the red gradient (for example “gap” or “14%”).
• Body copy is a muted silver-grey on dark and slate on light. Never long paragraphs in pure white.

07 · Content

Videos, blog images and social images

Same system, so a thumbnail, a LinkedIn card and the homepage look like one brand.

• Background: pitch black with a soft silver glow and a faint starfield with grain. Pearl is allowed for light variants.
• Headline: Sora, silver chrome on black. One red-gradient word or number as the focal point.
• Logo: Mention + glass diamond on black, bottom left or centred, at a consistent size. Never stretched, recoloured or placed on busy imagery.
• Imagery: editorial space metaphors (planets, signal, orbit, light through glass). No robots, brains, circuit boards or stock tech.
• Data in visuals: real numbers from the product only, labelled with the source and date. Engine logos keep their own colours.
• Video: black frames, slow silver light sweeps, red used once per scene for the thing that matters, the diamond as the closing frame.
• Never: blue or purple gradients, gold, neon, drop-shadowed white text, a flat red background, or the logo as plain text.
