Painting grass

Slap on a thick color, really thick, no water, no oil. This applies to both oils and acrylics. Using the flat side of a brush, lay it over the color and push up. Continue until you reach the desired effect but don't blend it too much. This will produce grass. Remember the grass in the distance is lighter than that in the foreground and there should be many value changes between the distant grass and the foreground. Fire in yellow and orange mixed with white for sunlight on the grass. Use darker greens or purples for shadows. Shadows almost always have purple in them. Use the same technique for sunlight and shadows. Remember, the paint must be thick for this to work.
