I know how to make the background transparent. What I can't find is a one or two click way to change black to white. I ended up having to spend over ten minutes trying to manually change a bunch of black pixels to white. I have other icons I want to be white. I'm trying to use a free tool like Pixlr but could install trial of Photoshop if needed.
Blending Option is best for changing colors of your Image If the background is transperant.
with the help of blending options you could change the color of image or icon into any color
- Double click or right click on your layer and select blending options. A layer style popup will open.
- From the Layer style menu Select Color overlay and pick your color. Smart and easy
CTRL+Backspace fills the background with main color, Alt+Backspace - Additional color
Ctrl+i or Cmd+i is the quickest way to do it. It just inverts all black pixels to white. It will also switch other colors to their complementary.
