It produces an attractive brassy-gold color that has exceptional permanence and has been used for architectual applications throughout the world.
*A »First Break« phenomena for ferri oxalate containing dyes is well known and documented in literature: Those kind of compounds show a fading after a short radiation time which then does not further degrade.
