Your orchid is registered as Blc Lui's Joyance.
Both parents are large 5-6 inch flowers bright yellow and 3/4 red lip. They both tend to circle the lip in red.
There were a lot of crosses of Blc Chunyeah in 2003 when this cross was made. Most do not vary much from the parent and I have not seen anyone re-making the cross since then.
The color variety on the pictures has no significance on a seed cross. All color varieties crossed are the same registered plant. The Tainan Gold in the picture has more red than is average for the variety.
