Googling around has just confused me as to which is which. I was wondering if what we have here is a miltoniopsis or miltonia. I'm pretty sure it's a miltoniopsis but I wanted to double check so I know we're treating it right. Also, the leaves on it are quite pale, but I think that's normal with miltoniopsis (especially one this white)?
Another confirmation that your plant is a Miltoniopsis, and it looks healthy. Assuming you are following normal fertilizer use with micronutrients I would have no concern about the color of the leaves.
