Using the Brush tool
It’s easy to use the Brush tool to paint in your document. Simply locate and select the Brush tool from the Tools panel, then click and drag in the document window to paint. You can also press the B key on your keyboard to select the Brush tool at any time.
To choose a different brush color, click the top-most color in the Color Picker Tool (this is known as the Foreground Color), then select the desired color from the dialog box.
