He followed the line of grouting that was flavescent with age and neglect. Gillian Slovo, Red Dust, 2000
Flavescent entered English in the mid-1800s. Its immediate source is the Latin present participial stem flāvescent- “becoming golden yellow, yellow” from the verb flāvescere “to become golden yellow, yellow.” The verb derives from the adjective flāvus “golden yellow, yellow.”
