Recolour images using MS paint, MS paint 3D or even photoshop (but not necessary)

I need somebody with basic understanding of browsing images on the internet and good with MS paint/MS paint 3D. Selected freelancer should find images on the internet (more details on the images will be provided later), save/download them, colour them in black and white using MS paint or MS paint 3D, or even photoshop if it is more convenient, however, MS paint would be more than adequate. I will need the original image as well as the coloured image. So, basically, find an image on the internet, paint them black and white, give me both images. The number of unique images can vary depending on the availability, maybe around 500 images to start with. A very basic skill on using MS paint would be more than enough. New freelancers are encouraged to apply. I will provide more details to the selected freelancer.
