Thanks so much to all of you for your time and efforts for helping me with ALL of your fabulous uploads...without your uploads it was impossible for me to create a decent set here that I was comfortable with posting.
I'm only able to upload one item at a time on mobile device....and that's only when it's working.
Here is a page which has solid color backgrounds.
Just click it on the color and the page will redirect to the solid color you choose to clipped it or you can download it and add to your items by the tag "add items".
I hope this is useful for everyone. ^^ https://www.solidbackgrounds.com
