Problem

When building a web application themed to match Delta Plus (the French PPE/safety equipment manufacturer at deltaplus.eu), the brand colors, logo description, typography, and design language are not documented publicly in a developer-friendly format.

Solution

Delta Plus brand identity uses a tight two-color system: primary accent is Supernova Yellow #FFCC00 (warm golden-orange yellow, not neon), paired with deep navy Firefly #11263B for structure. Backgrounds are white #FFFFFF or light gray #F4F4F4. The logo is a bold uppercase sans-serif wordmark 'DELTAPLUS' — text-based, no prominent triangle symbol. Typography uses condensed strong sans-serif headings (Roboto Condensed or Oswald style). Layout language: sharp 0 border-radius, strict rectangular grids, occasional diagonal section dividers. Navigation/footer use the dark Firefly blue with white text; CTA buttons use Supernova Yellow. The visual tone is industrial, authoritative, B2B. A lighter secondary yellow #FFE573 (Kournikova) is used for hover states. CSS formula: --brand-dark: #11263B; --brand-yellow: #FFCC00; --brand-yellow-light: #FFE573; --bg: #FFFFFF; border-radius: 0; condensed bold sans-serif for headings.

Why

Delta Plus's visual identity is semantically tied to their product: #FFCC00 is the same warm yellow used on hard hats and high-vis vests. The dark navy anchors the industrial seriousness. The sharp rectangular geometry mirrors the engineered, structural nature of PPE. Every design choice communicates 'trust this gear with your life' through contrast and visual density — this is why the brand feels cohesive even without detailed guidelines.

Gotchas

Do not use a bright neon/acid yellow — the brand yellow #FFCC00 is warm and golden-orange leaning, not fluorescent
The logo is text-only ('DELTAPLUS' bold uppercase) — no delta triangle symbol in the primary lockup despite the name
border-radius should be 0 or near-0 throughout — rounded corners break the industrial aesthetic
Red is NOT part of the corporate brand palette despite being a safety color — stick to yellow + navy

Delta Plus CSS custom properties / design tokens

:root {
  --dp-yellow: #FFCC00;        /* Supernova — primary accent, CTAs */
  --dp-yellow-light: #FFE573; /* Kournikova — hover states */
  --dp-navy: #11263B;         /* Firefly — nav, footer, structure */
  --dp-white: #FFFFFF;
  --dp-gray: #F4F4F4;
  --dp-text: #333333;
  --dp-radius: 0px;           /* Sharp corners throughout */
}

.btn-primary {

  color: var(--dp-navy);
  border-radius: var(--dp-radius);
  font-weight: 700;
  text-transform: uppercase;
  letter-spacing: 0.05em;
}

.site-header {
