Roberton Island - New Zealand

Greens family is a difficult colour, especially in landscape painting where we find also the blues family interacting with it. And the overuse of bright greens looks like an amateur painting. At a first look to a photo such as the photo 1 of the Roberton Island by RR, it seem to be easy to reproduce the nature in all its splendour but when it comes to harmoniously transfer it on canvas the colour mix becomes muddy and hence inexpressive. What did I do? Trying something unusual such as mixing black with yellow to get dark greens, burnet umber with cadmium yellow light for soft tones and eventually phthalo blue with cadmium yellow light to get vibrant tones………
