Also, this is a bit of an outlier, but I love [name_m]Carnelian[/name_m] “Nell” too. A few years back, in senior school, my [name_f]English[/name_f] class were given a creative writing assignment, to rework a fairy tale into a modern short story. I chose to rework [name_m]Little[/name_m] [name_m]Red[/name_m] Riding Hood, and I looked up shades of red to name my character, and chose [name_m]Carnelian[/name_m] (Nell). I’ve loved it ever since!
