How do you change the wallpaper and background to a solid background color

[anon(9983233)]

If your device has a list of wallpaper or background image options,

Settings > Home Screen

From here if there isn't any solid color options you can grab an image off the web and transfer this image to your phone.. which should end up being saved into your gallery or other location within you phone. This may take some searching within your device while the device is connect to your computer.

Update:

Although I'm not using a solid color as you've suggested I did a quick tutorial of how to locate, edit and add this to your devices list of images.

1) Locate the images within your search engine.. Use common phrases or words geared towards the color or image your searching for. In this case I'm searching for a "Carbon Fiber" home screen. I was able to locate the image via Page Resource:

2) Using the print screen option I was able to capture the image.. but I don't want to display the page source logo on my smart device. I edited this image via LunaPic.com

3) Saving this edited image to my computer via the photo albums:

6) Making sure the image was transfered, I located the image attached or saved to my external MicroSD card.

7) Entering the devices settings, I located the wall paper or home screen options, then located the edited & saved Carbon Fiber image to use as my home page and or wall paper.

I find it easier to just take a picture of the color background that I want. Once the photo is in the gallery, select it and then from the settings select it for the wallpaper
