Hello,
I would like to paint moss and algae in a dio but I do not succeed in getting the right green color. Is there anyone who can help me ? Thanks in advance.
Cheers

Color is pure experimentation. Mix it and test spray. Set aside some natural material to test on. Paint will absorb and change a bit on pourous material.
I would airbrush these types of material. Easier to control quantity and coverage.

When I paint moss or small leaves for tropical scenes, I paint with a brush. Several coats are neccessary to make sure the colour is fully absorbed and the material is saturated (to avoid the moss/leaf from 'sucking in' the colour).

It depends what sort of green colour you are trying to achieve. For tropical foliage, I use cheap student acrylic colours. I mix about 70% lime green with 20% brown with 10% yellow. This gives the material that bright green colour typical of most tropical broad leaved plants.

Hope this helps,
Chas

For moss or an accumulation of algae, I use really fine woodland scenics ground foam shoved down in sidewalk cracks or streets , the base of buildings, etc.Once its glued in place , I soak it with variuos shades of green thinned paint, dark green for old slime or algae and light, almost yellowish green for newer, around the perimeter and higher areas where moisture would dissipate faster, good luck

Thanks for your answers.

Salut,

For darker grass, Tamiya Olive Drab + Desert Yellow is a very good starting point.
For lighter green grass, Nato Green + Yellow works very well too.
