The variations in color of Butea flowers depend on many factors. By seeing Butea flowers from distance one can say with confidence about the water level or about last years rainfall. In Chhattisgarh near Dudhawa Dam region you can find Butea with nearly yellowish flowers. Because of high water level due to presence of big dam, Butea is showing different color. In the same area Shorea trees are dying prematurely due to same reason.
Just to add. I have documented seventeen different colors of Butea flowers and surprisingly every type of Butea color is of special significance in Traditional Healing. They differ in medicinal properties-the Healers claim. Hoping young researchers will come forward to conduct research on this unique aspect.
During last visit to forest I identified Butea population as 15 th type but the Healers traveling with me said it is 12 th type. May be I have to check my eyes. ;)
