This is a kind of pointless question, but I thought I'd throw it out there just out of curiosity.
Though Kopa's mane and tail tufts appear brown in The Lion King: Six New Adventures, adult Simba's mane and tail tuft are almost the same color in the books. Because of this, a few people have decided that Kopa's mane/tail tufts aren't brown, but red like adult Simba's.
I've personally thought that Kopa's mane/tail tufts are brown since Simba's tail tuft was also brown when he was a cub (speaking of which, there's a picture of cub Simba in "A Tale of Two Brothers", and his tail tuft seems to be about the same color as Kopa's). Still, since Kopa's mane/tail tuft are almost the same color as Simba's mane in TLK:6NA, I can see why some people draw him with a red mane/tail tuft.
So what do the good folks here at MLK think? Brown or red?
