I was thinking about this lately. I was drawn to the white bodied ponies a lot during childhood too- G1 Gusty, Starshine, G3 Starcatcher and Bowtie to name a few favourites.
But now I'm drawn to the super bright coloured ponies ! Any tropical, neon or celestial themes across generations. Also Blue or green bodies. Just received G3 Tropical Surprise in the post, and her colours are stunning
