Same here in terms of minimal marking. If I'd got things correct and therefore excellent marks, my teachers put comments like "Well done! Keep it up." I took that to mean I had done well and should keep on doing what I had been doing funnily enough. I did not need a multi-coloured dialogue with my teachers to understand that. If my work wasn't as good, I got feedback along the lines of "This needs improving by..." and I dutifully did whatever they had asked on the next piece of work. Or if I didn't understand I went and asked the teacher during a lesson. Again, no pink/green/red/fluorescent yellow pens needed. I don't get why nowadays marking needs to be so ridiculously detailed. Is there any proof it actually improves outcomes?
