Every gas carries a colour, set on the gas builder’s Label & Customization step beside its name. Once the plan is computed, that colour is how the dive profile tells one gas from another.
Choosing a colour
- Graph Color: a swatch carrying the gas’s current colour. Selecting it opens the palette.
- The palette: five colours, blue, green, yellow, orange and red, the same five the app draws plan data in.
- Custom: a colour field under the palette, for anything the five do not cover.
- The preview: a card under the control, carrying the mix name over a bar in the colour you chose.
Every new gas starts on the same blue, so a plan whose gases were added without touching this field is a plan of identical blue gases.
Where the colour is read
- The depth trace: drawn in the colour of the gas being breathed, so a switch is a change of colour along the line.
- The gas timeline: the strip under the chart, one band per gas in the same colour, in the order they are breathed.
- Each switch: a dashed vertical line and a label naming the gas switched to, both in that gas’s colour.
- The gas card: its dot and its mix name, and the card for that gas in the Gas Consumption view.
Watch for:
- Two gases on one colour still switch. The marker is drawn and its label still names the gas; what you lose is the reading at a glance, because the trace and the timeline no longer separate them.
- Two cylinders holding the same mix are one colour, whichever colours you gave them. The chart identifies a gas by its composition, so a second 50 % stage is drawn as the first.
