Wow, Yew Sung, what a wealth of information! Thank you.
Then, I think, the lighter yellow orchid, like you said, is more rounded and therefore, would be more representative of a Mokara Bota Gold.
Here's an interesting link from Ron (walingwaling). His Bota Gold does look like a cross between my two Bota Golds. http://www.rv-orchidworks.com/orchid...ld-orange.html
