Scarlett began as an English occupational surname for a dealer in fine cloth, later associated with the vivid red dye that cloth often carried. The name is commonly linked with boldness and vividness rather than subtlety -- a presence that's hard to overlook, more declarative than quietly reserved.
Give not judgment before thou knowest the intention of the querent; for many ask they know not what, nor can they express what they intend. - William Lilly (1602.-1681.)
