If I was underexposed it may negligible, at most 1/2 stop. But with Velvia whites are gray even properly exposed. Let me expplain (so I don;t get flamed). If you hold a Velvia slide side by side with the white object you photographed it will show a gray tint. If you hold it next to an Agfa RSX slide that photographed the same white object, you will be surprised that the white object is white in the Agfa shot and a slight gray in the Velvia, while Ektachrome will display a hint of yellow. Velvia being the most color saturated and highest contrast of the 3 may have formulated it that way to bring out more contrast (just a thought). I currently rate Velvia at ISO 32 on an ambient meter and 40 on a camera (TTL) meter.

I find velvia treats white pretty well, even if this film does sometimes lead to oversaturated slides. The problem with Velvia is that it adds a little 'punch' to reds even when this is not welcome, like when shooting early morning or evening scenes with the warmer sun light, or shooting portraits on a sunny day. On an overcast day, Velvia is a blessing. As to your taj mahal pics: may I suggest you have maybe slightly underexposed your slides ? It sounds like if you had exposed on the whites, bringing them down to gray (what you call 'green/grayish'). You have done this in bright sunshine, which also encourages underestimation of the exposure. My guess is that you were at least one stop underexposed. Intensive Velvia users advise to systematically overexpose it by a 1/3 stop, which is exactly the opposite of what is advised with the other slide emulsions. I've learned this here on the LUG, and it does usually help. Negs get 'fixed' by the lab at print time. maybe the technician just knew that the Taj Mahal was supposed to be white as he previsualised the neg... I've shot plenty of images with velvia that brought the whites out as they ought to be. Never tried RSX though...
