Brand identity guide · v1
The single reference for every brand visual. Each asset is shown on a
light and dark surface and downloads as SVG (vector) or
PNG. Colours are synced with
apps/landing/src/app/globals.css — base theme paper
#FBF7F4, broken by dark sections #1A1116.
#FF7AAC
Rose deep #E0447E
Ink #1A1114
Paper #FBF7F4
Typeface Archivo Black
The wordmark is the official logo. KADR takes the surface colour (ink on light, paper on dark), ELLA is always rose. No trailing dot. PNG exports on a transparent background.
The K alone in a square. Ink on rose (default) and rose on ink (dark UIs). Base of the app icon and favicon. PNG at 1024 px.
Tight stacked square lockup. KADR paper / ELLA rose and its inverse. For square supports (avatar, sticker, stamp). PNG at 1024 px.
Derived from the monogram. Below 32 px, the K only. Download each size as PNG, or the scalable SVG. Ink-on-rose is the default; a rose-on-ink SVG is provided for dark UIs.
Content is centered, domain sits top-right, accent line at the bottom. The bottom-left stays clear — that's where LinkedIn overlays the profile photo, so nothing important goes there.
Exports at 1584 × 396. Because everything is centered it also
crops cleanly to 1500 × 500 (X) and
1200 × 630 (share).
The og:image / twitter:image for link previews.
Fixed 1200 × 630: icon, wordmark, tagline and domain, centered.
Dark is the default; paper matches the site.
Exports at 1200 × 630 — the standard OG / Twitter card size.
The Open Graph image in 9:16 for Stories and Reels (Instagram, WhatsApp, TikTok). Same icon, wordmark, tagline and domain, centered with deliberately wide margins so nothing sits near the screen edges or under the interface overlays.
Exports at 1080 × 1920 — the standard story / reel size.
The exact site tokens. Rose only sits on ink or paper; for small rose text on a light background use the deep rose (contrast).
#FF7AAC · --brand
Accent & fills, on ink or paper. As text: large headings only.
Never rose-on-rose.
#E0447E · --brandd
Small rose text & links on light, hover state. Enough contrast on
paper.
#1A1114 · --ink
Text on light, dark section background (#1A1116). KADR on
paper.
#FBF7F4 · --paper
Default off-white background & text on dark. KADR on dark
surfaces.
One brand typeface: Archivo Black, uppercase, tight tracking (letter-spacing: -.02em). Interface body text stays in the system sans-serif.
Keep empty space around the logo ≥ the height of the K. Below the minimum sizes, switch to the monogram.
These break the identity.
Text you can copy straight into a profile or a post. Same voice everywhere: plain words, tutor to tutor, no jargon. Pick FR or EN to match the audience. Keep it as written unless a field forces you to cut.

Kadrella is the all-in-one software to run a private tutoring business, from a solo tutor to a small organization with several teachers. Students, teachers, schedules, recurring lessons, invoicing, payment tracking and messages (WhatsApp, Discord, email) live in a single tool. An assistant replies and books lessons for you, transfers reconcile on their own, and your Superprof students import automatically. You spend less time on admin and more time on your lessons and students. Hosted in Europe.
La plupart des profs particuliers jonglent entre un carnet, un agenda, WhatsApp et un tableur pour leurs factures. Kadrella met tout ça dans un seul outil. Les rappels partent seuls, les paiements se suivent tout seuls, et un assistant peut même répondre aux élèves. Et si vous gérez plusieurs professeurs, vous voyez tout au même endroit. On garde ce qui vous fait gagner du temps, rien de plus.
Most private tutors juggle a notebook, a calendar, WhatsApp and a spreadsheet for invoices. Kadrella puts all of that in one tool. Reminders go out on their own, payments track themselves, and an assistant can even reply to students. And if you manage several teachers, you see everything in one place. We keep what saves you time, nothing more.
