The hierarchy to the left in Hazard and Risk Resister uses grey font colour for Hazard Areas and black for Hazards.
For people with a bit worse vision, with lower contrast monitor settings or sitting in a room where some light reflects off the monitors - it can be hard to distinguish these two things.
Some change to font colours should be made; even if it is just matching the look to how the hierarchy looks in the Setup (Hazards are blue in there).
