Blue is the color of the clear sparkling sky, which in the curent monsoon season is a rarity. Infact the dull gray skies brings on melancholia. After the initial euphoria of the rains. the perpetual grey canopy does seems boring. One longs for the clear days of spring and autumn.
Blue is also in prominence among the water bodies. clear blue lakes and seas, exude vivacity. just as Brooke Shields did in Blue Lagoon.

So it had to be Blue which I chose for my new template.
