Deep Red, Crimson
In this construction project, they will be using thread to hold everything together. The color of the thread is a deep red, and it gives everything a crimson look.
Because thread isn't that strong, you have to use A LOT (to hold things like beams in place). So, the deep red / crimson thread actually stands out a lot in this construction project.

You're done, and the whole building is a deep red crimson color (it takes a lot of thread to hold a whole building in place). It's time to show the client, Emperor こういち, the finished product.
こういち walks up with a big smile on his face. "I love the color crimson!" he exclaims. "It's the same deep red color as my enemies." Hint: When you see 工 in a kanji it will often take the こう reading.
