add a small amount of black paint to the green paint (if it is paint or liquid of some sort) and mix it well. you can vary the darkness by adding more black paint.
Dark green and red make a brown or earthy color when mixed together.
i think its dark green :D
Depending on how dark the green was, the yellow would make the green lighter or it would be absorbed by the dark green as if you didn't mix anything into it. The darker a colour is the harder it is to lighten.
It will make a deep color teal.
very dark green
Brown
Brown
Dark Red (of course)
Viridian (Dark spring green).
Combining green and magenta will produce a dark purple color.
Green and dark brown mixed together typically create a muddy olive green color.
its just a disgusting shade of dark green. mix dark blue with it if you want a dark green that doesnt make people depressed.
