[Image ID: Three pictures of a foliage coloring tutortial drawn digitally. The first one shows a bush drawn with a blue-green undertone, a green midtone, and a yellow-green highlight, with color swatches next to it. Accompanying text says: “Plants reflect the color of their environment. Leaves in particular are transluscent, and so therefore foliage is heavily affected by lighting conditions and its surroundings. A healthy bush in direct sunlight will probably be yellower at the top and bluer towards the base.”
The second image shows three smaller bushes all juxtaposed, and a separate example patch of grass underneath. The first one is a paler olive green bush with a brown undertone and a desaturated yellow-green highlight. The second is a yellow-green bush with a red undertone and pink and muted yellow highlights. The third is a teal bush with purple undertones and teal and purple highlights. The grass underneath is a pale yellow with clumps of green in it. All images are depicted with color swatches next to them. Accompanying text says: “Of course, plants can have other undertones too, such as brown, red, purple… Grass can also be not pure green.”
The third image is a single illustration of a green tree that’s been given rendering with soft lighting and shadow. Accompanying text reads: “and if you put lighting (on anything but especially foliage) the shadows will be of the complimentary color of the light. Yellow light? Purple shadow, just like how how on sunny days your own shadow looks blueish.” There are two swatches of yellow and purple to show what colors were used to render. End ID.]
