Crimson
Crimson was a color he was used to seeing. After all it was his brother's color. But for some reason he was noticing the color more and more in the past few months and it scared him.
Although technically they weren't blood brothers but that was just a technicality. A technicality that would cause Blake to kick his ass to the moon and back if he found out his brother liked him like that.
This was why Blake was keeping his fascination with the color crimson to his self.
