Do’s and don’ts

Rules written from the measurements, so a coding agent stays on style.

  • Use #FFFFFF for the page and lift surfaces in small steps: #FFFFFFF2, #FFFFFFE6, #FAFAFA, #DFF8FF.
  • Keep text in 4 levels: #000000, #171717, #333333, #4C4C4C.
  • Reserve #00C3FF for primary actions and key highlights.
  • Reuse the measured spacing steps (8px, 16px, 20px).
  • Use 12px corners on most elements; larger surfaces also use 20px, 27px and 30px.
  • Introduce new font families beyond ABC Solar Display and TT Norms Pro.
  • Use #00C3FF for large backgrounds or body text.
  • Make interface transitions slower than 0.3s.
