This would be extremely helpful for recolouring!

This is a quick glance at how I do it using Photoshop:
1. Convert the image to CMYK mode.
2. Select only the key (Black) channel from the channels panel.
3. If the black lines show too washed, use the "levels" control to darken them.
After that, you can select all (Ctrl+A) and copy that channel to a new image for editing. The result is all the darkest lineart isolated from the original image.
Take into account that it may show some darker shadows too, as some bricks and parts of the conical roof in the last picture. You can solve that by using several methods: eraser, magic wand, burn/dodge tool, brightness/contrast, levels, etc.
Hope that helps you!
