Piskel: Resize the drawing area

---

To resize the drawing area follow these steps:

1. On the right-hand side menu, click on the 'Resize' tab.
2. Uncheck the 'Maintain aspect ratio' if you want a different width and height.
3. Enter the width and height that you want.
4. Click 'Resize'.

The drawing area will resize to your chosen width and height.

Think about the color wheel you learned about before. Choose a base color for your background. Click on the color picker on the right side of the screen and select your desired color.

Now, use the 'Paint Bucket' tool to fill the entire canvas with your chosen base color. Click on the 'Paint Bucket' icon and then click on the canvas to fill it with your selected color.

Complementary colors are colors that look good together because they are opposite each other on the color wheel. For example, red and green are complementary colors. To choose complementary colors for your background, look at the color wheel and find the color that is opposite your base color.
