This is a 5 step process:
- Create a new document (File > New)
- Set the size to 8in X 8in @ 72dpi and white background
- Define your entire selection area
- Fill the defined area with a color (any visible color)
- Save as jpeg and upload to your blog with comments
You cannot:
- Use Layers
- Select and fill an area more than once
- Select and delete an area to drop out the color inside an area
- Add to your selection by holding down the shift key
- Subtract from your selection using the ALT key (option on the Mac)
