Australian Lotto Ball Colours

Physical draw balls

The four Australian lottery games each use a physical lottery machine with numbered balls. Across all games, the numbered balls used in the main draw are white with the number printed on them. There is no colour-coding of the physical balls by number range — every ball looks the same in the barrel.

The only visual distinction in the draw machine itself is when Powerball uses a separate barrel for the Powerball number — that barrel and its balls are a different colour from the main barrel, making it visually clear which number is the Powerball.

How G Network uses colour

On this site, each game has a distinct accent colour used throughout the results pages, ball displays and statistics. This makes it easy to recognise which game you're looking at:

Main numbers vs supplementary numbers

All single-barrel games (Saturday Lotto, OzLotto, Weekday Windfall) draw both winning numbers and supplementary numbers from the same barrel. On G Network results pages, the visual distinction is:

• Main numbers — plain outlined balls (unfilled)
• Supplementary numbers — lightly tinted filled balls using the game's accent colour

For Powerball, the 7 main numbers are shown as outlined balls, and the Powerball is shown as a solid filled ball in the game's red accent colour — matching how the separate Powerball barrel is visually distinguished in the live draw.

Statistics page highlighting

On the statistics pages, ball frequency cells use a heat map to indicate how often each number has appeared:

• Hot (amber border + tint) — drawn more frequently than average over recent draws
• Warm (blue border + tint) — drawn slightly above average
• No highlight — drawn at or near average frequency
• Cold (reduced opacity) — drawn less frequently than average

These highlight thresholds are relative and based on draw frequency over the full available history, not a fixed rule.
