You can change the appearance of any object with a closed path using a fill. By filling an object, you apply colors or patterns to the inside of its borders. If you leave an object without a fill or remove its fill, the object becomes transparent. The following fills are available:
Uniform fills are the most basic fills. When you apply a uniform fill, you
give an object a solid, or uniform, color. You can quickly fill an object with a
solid color using the Color Palette.
Fountain fills display a progression between two colors following a linear,
radial, conical, or square path. You can use the preset fountain fills to
simulate the appearance of neon tubes, metal cylinders, and a variety of other
real-life objects.
In all cases, you can apply fills to specific objects or set defaults so that every object you draw has the same fill.
