This rhyme comes from Cassandra’s Clare The Mortal Instruments series. The following rhyme is a Shadowhunter’s nursery rhyme.
“Black for hunting through the night
For death and mourning the color’s white
Gold for a bride in her wedding gown
And red to call the enchantment down
White silk when our bodies burn
Blue banners when the lost return
Flame for the birth of a Nephilim
And to wash away our sins.
Gray for the knowledge best untold
Bone for those who don’t grow old
Saffron lights the victory march
Green to mend our broken hearts
Silver for the demon towers
And bronze to summon wicked powers.”
– Cassandra Clare, City of Heavenly Fire
