Sorry for the question. I am new to graphic design. I am a developer. I just bought an icon bundle for iOS & Android applications. I found that the colors are only black & while. The icons come with some formats such as PNG, PSD. I just want to modify icons colors. I only used Windows Mspaint application before.
Can someone guide me how to do? What software do you recommend?
How can I extract an icon from set of icons in a big PNG file?
Note that the purpose of using these icons is for iOS & Android applications.
