Have you ever wanted to change the color of an image? It's not hard and you can do it within seconds on any modern day image editor. I will be using Paint.net because it's free, offers a wide range of plugins and is easy, yet powerful to use. You will NOT need a plugin to change the color of an image. Here we have an image of a red car.
We want to find the hue/saturation option. It is located in the adjustments section of Paint.net.
Once you have found the hue/saturation option you will be prompted with a window that looks similar to the one in the image. Just slide the sliders up and down until you find the color you want! Here is our finished product after we turned the red car into a green car.
