If you want to just convert the format, the following method will help you:

In python3, using PILLOW and Numpy:

From PIL import Image
import numpy as np

im = Image.open(path/to/image, 'r').convert('L')
im = np.stack((im,)*3, axis=-1)
im = Image.fromarray(im)
im.save(path/to/save)

Some ways of doing so is to train a neural network, but for that, you need to have a dataset of B/W and colored images. Here are some approaches:
