Marking on Coloured Asphalt Requires a Contrast Check — Dark Grey on Light Grey Doesn't Work
A Rowville technology business park carpark had been laid with alternating coloured asphalt bays — dark charcoal and light pearl grey — as a design feature. The developer asked us to use matching-toned lines: white on the dark charcoal bays, grey on the light pearl grey bays for a monochromatic aesthetic.
We marked as specified. The white lines on dark charcoal read perfectly. The grey lines on light pearl grey were barely visible — the contrast ratio between the grey marking colour and the grey asphalt was insufficient. Drivers were having difficulty identifying bay boundaries in the light grey sections, particularly in overcast conditions.
We returned and remarked the light grey bays with white lines instead of grey — white on light grey produces a contrast ratio well above the AS/NZS 1428.1 30% minimum threshold. The developer accepted the change; the overall aesthetic was still clean. But it was a second session that shouldn't have been needed.
Any marking on non-standard or coloured asphalt surfaces requires a contrast check before the marking colour is confirmed — the same principle we apply to accessible bay shared zones. For Rowville and other technology park locations where coloured asphalt is common as a design element, we now specify the contrast calculation for any proposed marking colour on any non-standard asphalt before agreeing to the colour scheme. VicRoads approved.

Frequently Asked Questions
Yes. Rowville Knox City EastLink corridor technology parks and business parks are part of our south-east Melbourne schedule. Coloured asphalt contrast assessment on every non-standard asphalt carpark — inadequate contrast triggers colour revision before marking begins. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Rowville quote includes a site assessment, surface condition report, and fixed pricing. No estimates that change at invoicing. For WorkSafe Victoria improvement notices we can typically assess within 24 hours and deploy within 48-72 hours. Completion comes with photo documentation, a compliance statement, and material specifications. VicRoads approved for any road or carpark marking that requires local council or state road authority sign-off.
The contrast ratio between the marking colour and the asphalt surface must be sufficient for drivers to clearly identify bay boundaries. Grey on light grey produces a low luminance contrast — often below 15%, well below the AS/NZS 1428.1 30% minimum and below the practical visibility threshold for driving conditions. White on light grey typically achieves 40-60% contrast depending on the specific asphalt colour.
Any colour is possible, but the contrast between the marking colour and the asphalt surface must be verified. We calculate the luminance contrast ratio for your proposed colour combination. If it's adequate, we proceed. If it's insufficient, we recommend an alternative that achieves the required contrast while meeting your aesthetic objectives where possible.

AS/NZS 1428.1 specifies 30% minimum luminance contrast for accessible area delineation. For general carpark bay marking, practical visibility requires at least 20-25% contrast under typical viewing conditions. We target 30% or above for all marking on non-standard surfaces to provide a safety margin.
