This crossword was born from the "American Tire Depot" sign in the header! I realized it was red and also had the word red hidden in its name. Then, a couple of days later, I was watching Daredevil: Born Again and noticed the word red in the title at the end of the title sequence. Big red letters with the word red in it. I was over the moon.
In my search for more red things with red in their name, here's what I came up with (aside from what you've already seen in the puzzle):
ANGERED: seeing red... HATRED is different but similar.
ADORED: love is associated with red, but it's a stretch to say "adored" is red.
RUBY ORE DEPOSITS: this was a candidate for a 15-letter gridspinner, but it's not as natural because "ore deposits" aren't inherently red and need the qualifier of a red mineral.
That's all I got, but if you guys can come up with any more (Maybe even for another color) I'd love to hear them!
