金楼閣 (Kinroukaku)
 

http://www.orchidboard.com/community...1&d=1612948594

A golden yellow-leaved cultivar. New leaf begins as normal green, but under the adequate level of light, yellow pigments overpower green chlorophylls and the leaf will turn beautiful golden yellow, with slight green tints at the underside and base of the leaf. Just like Fugaku, selfings of original Kinroukaku are known to produce almost identical plants.

Hmm... what color is the base of the stem and active root tips on your plant?
