Oncidium Leaf Color

[tim abbott]

I don't know what kind of oncidium this is. The medium is a standard orchid mix, mainly piecies of bark about 1 to 1 1/2 inch long. The pot has three prominent slits on the bottum for drainage. I keep the plant outside & it gets well diffused light. I water about once a week, fertilize every third time or so with water soluable orchid food. The plant currently has two flower spikes. My question is the pale green color of the leaves normal for some oncidiums? I have another oncidium & it has dark green leaves.
