A client asked me recently if the icon colors could be changed. Of course I knew there had to be a way to change or customize the icons that Ning serves us. So, this is the quick and dirty way to change the color of the icons. I added a single pixel stroke and a faint drop shadow to the icons to make them stand out. The original sprite image can be found sprite.png.
How to Over-ride the default icons on your Ning 3.0 network
First Choose a Premade Sprite Image (right click and copy image URL or download and reupload to your own network through a text box)
*If you need another color, let me know the HEX# in the comments below and I'll make it and upload it for you.
Second, now add the following CSS to your Advanced CSS box in Design studio and replace the red url with the sprite image you chose above. Note: If you'd like to use white icons with a single black 1px stroke, just copy and paste the following into your CSS as is.
Now you are done! Enjoy your custom icons!
