In the investigation of quantum chromodynamics Green functions are a useful means to bridge the gap between elementary fields and the emergent physics. Important for the progress in recent years was a good understanding of Green functions in the vacuum. Here we use functional methods for the calculation of correlation functions and investigate how large the errors induced by modern truncation schemes are. For this we calculate three-point functions and include them for the first time also dynamically into the system of truncated Dyson-Schwinger equations, thus reducing the dependence on models.
