This colorful illustration depicts a bountiful apricot tree. The ripe fruits are a beautiful and vibrant orange color, the perfect symbol of summer. To really bring the fruits of this tree to life, I would use multiple shades of orange and yellow. Start with a light yellow at the top of the fruits, and layer a slightly darker orange in the middle. I would also use a lighter orange for highlights, to make the fruits look plump and juicy. For the foliage of the tree, I would use lightly blended shades of green and brown. Adding some white to the tips of the leaves will give the image a little extra dimension. Finally, do not forget to add some shadows to the fruits to add realism and definition to the image.
