Using the colour palette
The colour palette displays the current foreground and background colours. To pick a new colour, click the corresponding square in the colour palette and choose a new colour using the colour picker.
- To swap the foreground colour and the background colour, click the two-headed arrow in the colour palette. Alternatively, you can press X on the keyboard.
- To reset the colours to the default black and white, click the small black-and-white squares in the colour palette. Alternatively, you can press D on the keyboard.
Further, there are two keyboard shortcuts related to filling using the colour palette:
- Alt+Del fills the image (or the selected region) with the foreground colour.
- Ctrl+Del fills the image (or the selected region) with the background colour.
