  Specialty Exteriors website stylesheet

  The colour palette is based on neutral, muted tones with high
  contrast – a hallmark of sophisticated, luxury branding【867747108657072†L40-L47】.
  Gold (#d9b061) paired with dark navy (#0f1b27) and soft neutrals (#f2efea)
  conveys exclusivity and professionalism. Typography uses the Montserrat,
  Playfair Display and Open Sans families, which are recommended for
  legibility and elegance in modern websites【500587778167273†L122-L163】.
