Gold on green...observations

I am posting my observations from 'Gold on green'.

Correct me if I am wrong...

1. More exposure needs to be set for yellow lighting when compared to white-fluorescent lighting.
2. The gold gets more predominant in yellow lighting.
3. So, if we are taking portraits, it is better to maintain fluorescent lighting
4. And in case of jewelery advertisements, it is good to give a yellow lighting like in GRT's ad (Golden girl)

I kept the exposure at f/2.6, macro-mode throughout the exercise.

P.S. Thank you friends for pointing out that observations should also be shared...
