I can post some better pictures here in a bit. I thought they seemed lighter than anything else I found that was blue. Some poster on Reddit said they were blue so I assumed they were correct. They are a very tactile switch. I can also post a video. Either way I am happy with them I just couldn't find anything that said use this PCB and case and it would work so I didn't want to gamble and be wrong.
EDIT- I didn't answer the layout question. I think I like my smaller board at home but with that said I wouldn't mind a full sized board. Not sure of what they typically call them.
The big tell for blue alps is the clicky-ness, there's nothing quite like it out there. It is true that they do look light, but that could be easily explained depending on where the switches come from originally, how the board was stored, and what the board actually was that the pcb was pulled from. Any idea about that?
My recommendation for a smaller board would be the
GSKT-00 which is entering into groupbuy within the next couple weeks, and is a very good price for what it is. That board has options for alps compatibility and could be a great home for the switches.
As for fullsize boards, there are a lot of options out there, but one very recent board is the
hbcp by Hineybush, which is an 1800 compact layout. It has alps compatability as well, but the groupbuy is finishing up right now and will be delivered to buyers soon, if they're not shipping already. I would look out for extras of that board or check mechmarket once people receive them. There are bound to be some people selling.
