You can choose from different effects such as negative, greyscale, flip, and mirror. You can also set image brightness and transparency levels from this window.

If the aspect ratio of the image you chose is different from what is required, you can click and drag on the rectangular frame on the image preview to choose the desired portion of the image. After you’ve done this, click ‘Next’ to continue.
STEP 3. Choose An Image For The Start Menu
Here, you have the option of using the same image you chose in the previous step, or you can use a different image. If you choose a different image, you can again set the image attributes by clicking ‘Modify this image’.
Choose a Start Menu image
Remember to choose the appropriate portion of the image by dragging on the frame in the preview. Click ‘Next’ to continue.

The next screen lets you specify custom colours for various screen elements such as Today text, navigation bar, command bar, navigation tray, message, and more. Click on the drop-down to choose the specific element, then click on the colour options below to bring up the colour palette. 
Customise the colours for your Today Screen
You can now choose the desired colours. Click ‘Next’ after you’re done.
SETP 5. Save It
