Hey

The Benedict's test is both a quantitative and qualitative test. Qualitative in the sense that the colour of the precipitate will give you an idea of the quantity of sugar present in the solution, but quantitative in the sense that the colour of each precipitate can give approximate values of the concentration of sugar in the solution:
A greenish precipitate indicates approx. 0.5% concentration; yellow precipitate indicates 1% concentration; orange indicates 1.5% and red indicates 2% or higher concentration.

Hope that helps!
