[PyGame] image color

[nilamo]

Once you've loaded the image as a surface, then you can access that surface's pixels with a PixelArray.  The PixelArray class has a replace method, which replaces all instances of one color with another (so you don't need to check individual pixels yourself).  When you create a PixelArray, it locks the underlying surface until it's garbage collected, so you should delete it when you're done (or use a function and return from it).

So...

surface = load_image() # ...whatever you're already doing
pixels = PixelArray(surface)
pixels.replace(Color(255, 255, 255, 255), Color(0, 0, 255, 255))
del pixels
