I think your observations make a lot of sense! I see this often. When you get dentures, the tissue will blanche and lighten in color — only the areas supported by the denture, that is. Sometimes, there is a yellowish cast, as you mention.
There’s nothing you can do about this lightening, and it’s normal, but the yellowish cast, I believe, is a reaction to food getting caught underneath the denture. I would recommend cleaning your denture as often as possible and perhaps washing it morning and night and never leaving food underneath the denture if that ever happens.
