For those with colour screens the images are in colour. Whilst
retracing the surveys the colour scheme has evolved. The following is
the current list of colours and their associations.
| Black | Titles |
| Blue | Passages(both plan and elevations) |
| Green | Scales, compasses and anything relating to the way the survey was put onto paper |
| Magenta | Cross-sections |
| Red | Pitches and the corresponding lengths |
| Light Blue | Water(no distinction is made for sumps) |
