I am trying to make an arrow that will stand out against any background. I know there are ways to make transparent and semi-transparent images.
I was wondering if there is a way to make a layer that actually inverts the background (something like a mask I think). So when I place the image over some other graphic, the specified portion of the image will have a background that stands out. I am planning to use this arrow on a website.
I am just a beginner, sorry if this is obvious / obviously impossible. Thank you for your time :-)
