Duality between the coloured quantum group and the coloured quantum algebra corresponding to GL(2) is established. The coloured functionals are constructed and the dual algebra is derived explicitly. These functionals are then employed to give a coloured generalisation of the differential calculus on quantum GL(2) within the framework of the R-matrix approach.
