It's clearly a very different process, the old comics were colored in the largely pre-digital world so it would have been a matter of him handing a B&W image to the syndicate, who then colored it by laying down a very limited set of flat tones. Probably by cutting out bits of zipatone and manually making the cyan/magenta/yellow plates after a quick watercolor sketch of what colors they wanted. The strip ended in 1995, when Photoshop was version 3. Not CS3, that's actually v10. Version 3. Distributed on floppies. The new ones are very much My First Digital Painting; you can see him experimenting with leaving the ink lines behind in the taxi and cub scout pieces, but keeping them in the alien piece. He's got a lot of tools to get the hang of before he settles down into a regular style, if he ever does - dude's seventy years old and retired, he ain't gotta treat this as more than a hobby if he doesn't want to IMHO.
