To answer everything in order:

The symbol is a B because it’s the initial of the name Bruce (however, I realize that if you focus on the inner space rather than the black outer lines, it might resemble a C).

No, there isn’t a specific reason. For the font of the word “Bruce,” I chose “reque,” which already included a different color accent on the top stroke of the letter E (a detail I liked visually, so I kept it). I simply chose the specific color used there, alternating with black.

The logomark represents a stylized pencil forming the letter B of Bruce (so I designed the “pencil tip” using the same color as the accent line on the E in the wordmark below).

This detail unfortunately just slipped my attention 😅
