Got it, let’s make that screen the equivalent of a tool chest with no missing parts. First, each icon gets a 48×48 pixel grid, all centered, with 12px padding from the edges. That keeps the layout “tight” but not cramped. Second, color‑coding is the only way to avoid a crew staring at a green icon thinking it’s a safety hazard. Use a single‑tone palette: red for critical, orange for warning, green for normal, each with 60% saturation so it’s readable even in bright sunlight. Third, group by function: HVAC on the left, electrical on the right, each with a subtle gray divider so the eyes don’t have to chase. Finally, add a tiny tooltip that appears on tap, showing the last‑maintenance date, so the crew can see if they’re dealing with a fresh alert or a stale one. That’s the “pixel‑perfect” view that keeps people from accidentally stepping on a red flag.
