Hi Faith,
Thanks for contacting us!
To change the color of your entire picture, you can use the Effects tab > Tint effect (around 2 pages from the top of the tab). To change just an area of the picture, use the Effects tab > Doodle tool (towards the end of the tab) to paint over a particular area. You can use the Advanced Modes dropdown within this tool to make the effect blend with your image. You can try all the different modes, but you will probably want Overlay.
To remove a background from your image, you can either use the Doodle tool (mentioned above) to paint a flat color over the background of your image, or if you’d like to replace the background:
1. Upload the background image you would like to use
2. Drag on the foreground image (that you want to remove the background from) from the Photo Basket at the bottom of the editor
3. Click the Eraser Button on the Photo Properties dialog that appears
4. Erase the background by dragging over it with your mouse button down
Let us know if you have any further questions!
