In this tutorial I will explain how to use the gradient tool in detail. To begin, a gradient is basically two colours blended seamlessly together. The gradients can contain a blend of one single colour, or a blend of multiple colours.
The gradient tool is located in the same place as the paint bucket tool. To use this tool you simply drag out a line representing the direction of the gradient. The first point defines where the first colour will end, and the second point defines where the second colour will begin. The example below shows the gradient from left to right. The number one shows the first point of the gradient.
(You can hold down the Shift key to constrain the gradient to right angles.)
The length of the gradient defines the width of the gradient. So, a small length will give you a small gradient and a long length will give you a long gradient. A long gradient gives a more blended look while a short gradient will give you a more defined look. Below is examples of a long and short gradient.
