[1.1.77] migrating to color setting doesn't default + other "issue"

[Honktown]

changing a string-setting to a color-setting does not reset the color to default (there's the button for default'ing, thankfully)

Other issue: other values (string, number) are not an error. I'd expect them to be.

Thanks for the report. Both issues are now fixed for the next release.
