Same business, two different looks. Open each on your phone and your laptop, and tell me which feels more like "a family you'd trust with your memories." Everything here is placeholder art (no stock, no AI); real family photos would replace it.
Mostly black-and-white and warm paper, with color arriving where the memories are: the restored photo, the logo, the button. Your black-and-white-to-color idea, built into the whole look. Nostalgic, restoration feel.
Open Mock A ›Near-white and airy with one calm accent, and the family photos supply all the color. Photos shown as Polaroid frames (your Polaroid idea as the motif). Clean, modern, gets out of the photos' way.
Open Mock B ›Both fold in the logo idea (a photo dissolving into particles, i.e. digitizing) and the "let the real photos be the color" thinking. Neither has a family face yet, that's the next real asset and it comes from an actual photo of you two plus dad's job.
For reference, the current live site is at hoeck-family-archives.pages.dev (the "How it works" jump bug is now fixed there too).
If neither direction lands, I have five more to try (Kodachrome, photo album, darkroom, projector night, neutral gallery). Just say the word.
