                 Photoshop provides five types of gradients which are as follow:












                   Linear Gradient              Radial Gradient             Angular Gradient         Reflected Gradient        Diamond Gradient
                      Paint Bucket Tool

                 The Paint Bucket Tool in Photoshop fills adjacent pixels that are similar in colour in the image. It fills
                 with either the selected foreground colour or with a pattern. If the image has flat colours, then there
                 will not be any issues while filling colours. But if the image is complex and has a lot of colours, then
                 paint bucket tool will not be of much use.
                 Follow the below steps to use the Paint Bucket Tool:
                 Step 1:  Create a new document or image with similar colour or pattern.

                 Step 2:  Select the Paint Bucket Tool from the Tools panel.
                 Step 3:   Select a mode from the Mode drop-down list in the Options bar. In this case, we have selected
                         Linear Burn mode.
                 Step 4:   Set the Tolerance value in the Options bar. The Tolerance value directly affects the pixels to
                         be filled with colour. A low Tolerance means only very similar colour pixels will be affected and
                         high Tolerance means more pixels will be affected. The range of Tolerance is 0 to 255. If the
                         Contiguous option is checked, only pixels that are connected to the original pixel are filled.
                 Step 5:   Select the desired foreground colour and click on the image. The similar colour pixels are
                         changed.
