I have a set of
.png images (which are controls like buttons, sliders, checkbox etc for a GUI) and I'd like to convert a specific color to another for each files using an automatic solution.
For example, let's say that my input are theses three files
button_small.png button_medium.png button_large.png
which are yellow buttons with a black stroke.
I'd like my output to be the same (name, paths, sizes) but with the yellow color (or hex value) replaced by orange color (or an other hex value).
Is there any solution, like a script or photoshop tool ?
