does anybody know which hoya has bright red flowers?

i was looking at vermonthoyas site and there is a banner with different pics right on first page: it's the bottom left corner, first one.

i started going thru the the list of pics one by one but it takes a long time to get thru all.

i googled, but nothing comes up that is so vivid red. not salmon, not burgundy, not pink.

it must be something rare?

i took a tiny snapshot of it for reference
