Hibbertia coloensis is a much-branched shrub that typically grows up to 1.5 m high and 2 m wide. The leaves are linear to lance-shaped with the narrower end towards the base, 8–13 mm long and 1.2–1.6 mm wide on a petiole 0.3–0.7 mm long. The flowers are arranged singly in leaf axils on the ends of branches on a peduncle up to 4 mm long, with oval bracts 7–8 mm long. The five sepals are joined at the base, the two outer sepal lobes 10–12 mm long and the inner lobes 6.8–7.5 mm long. The five petals are egg-shaped with the narrower end towards the base, yellow, up to 14 mm long. There are twenty-four to twenty-six stamens arranged around the three hairy carpels, each carpel with six ovules. Flowering has been observed in October.
