Today, Wally West is famously ginger (red-haired) and his hair color is a key part of his visual identity, but for years during the Silver/Bronze Age when Wally was Kid Flash, his hair was colored inconsistently. Sometimes, colorists gave it a reddish hue, but just as often, Wally's hair was colored brown. Because hair color was shown visually, but not discussed or described verbally in the old comics, when did it become clear that Wally actually is a ginger and not brown-haired?
