Two Paphs need IDs

[shadytrake]

Hi all.

In assisting the local Botanic Gardens with caring for their orchids, I have come across some that have lost their tags.

These 2 nice Paphs need some ID help.

1 is the yellow
2 is the yellow's foliage
3 is the burgundy
4 is the burgundy's foliage (you can see the new growth)

As FYI, they were obtained by the gardens in the last 10years and they were probably a readily available cross rather than a hybridizer's rarity.

Also, the yellow one looks kind of peachy but that is because of my iPhone. In real life, it is pure lemon yellow and really bright.

Any IDeas?
