Sweety Colorful Rio series is famous for its iridescent nature. The mix of colors reflect light, add a brilliant sheen and seems to shift between shades. The subtle fusion of multiple colors holds the series unique. Sweety Colorful Rio pink appear very sophisticated against brown eyes. Due to the translucency, pink color is overpowered by the intensity of brown eyes. They rather appear purple/blue. Check the review if the photos interest you.
