Nevertheless I have to add that, working in cmyk most of the time, I tend to be very happy with the brightness one can get in greens. The recepe of 100% yellow with something between 50% - 75% cyan gives very nice greens in print. Getting rid of magenta and too much black, and crank up that yellow can be of great help to get some eatable green in your veggies (actually, in Dutch, vegetables are called 'groenten'. Groen being the word for 'green'). The selective color adjustment layer is great for regaining vitamines. In your photographs of food and nature.
