A coloured driveway gives the property a distinct finish without giving up any of the strength of standard concrete. Where pigment is mixed through the batch, the colour runs the full depth of the slab rather than sitting on the surface, so it will not wear off under tyres or bleach out after a summer of Toowoomba sun. Expect some natural variation in tone across the surface — that is a normal characteristic of integrated colour and part of how it reads, not a defect. Placing and finishing take more care than plain concrete to keep that variation even.
Sealing is strongly recommended here. It shields the pigment from the strong UV that comes with sitting 700 metres up, slows the moisture cycling that winter frost turns into surface damage, and keeps the driveway looking fresh. Coloured concrete sits equally well against a rendered contemporary build at Highfields and a red-brick interwar home in East Toowoomba.
