Might be the light then.
I gave mine away but I visited and saw it.
It changed for the better.
The flowers got larger, although not as large as they once were, and the color intensified as well.
Still, the color was too pale, but my friend keeps the plant in the dark livingroom and that could be why.
The tessellation is much lighter than last years.
Well, most likely, I wont' get it back because my window space was quickly replenished with other plants. haha and much less maintenance.
I wish I had a greenhouse to hang vandas of all colors and just let the roots dangly down, so I don't have to worry about the watering and carrying them around breaking my knees and back. lol
