The Colquhoun Grevillea is a root-suckering shrub growing to 1.8 m tall. The species grows in an erect and open, or low and dense, form. The leaves are ovate, alternate, up to 44 mm long and 18 mm wide. Leaves are hairy, grey-green above, with the lower surface almost white and densely hairy. Leaf margins curve under, sometimes almost obscuring the lower surface. Flowers are red and yellow with curved tubes about 12 mm long, hairy on the outside, densely hairy inside, splitting into four petals to release a red, hairy style which measures up to to 25 mm long. The fruit is a leathery, hairy capsule with longitudinal ridges, which split to release winged seeds.
