These are nice areas surprisingly close to the N'pton conurbation. All except the shot of what is mainly boats and water look to have a slight magenta cast in the sky area. It might be my monitor of course. Are these home scans of negs or scans of home produced prints or slides?

You're right of course: there is a slight magenta cast.
It could be removed, but subject to the rules of 'uploading' I've done nothing
