25. Green
Castiel had known his favourite colour for years. It seemed like such an insignificant fact to know about oneself – what did it matter if somebody liked yellow and another liked purple? Colours were colours; simply the wavelengths of the electromagnetic spectrum that humans could perceive. But now, as a human with limited perception, Castiel could see just what was so attractive and alluring about colours.
If asked, he would always say that his favourite colour was green – the same deep, vibrant shade of green that he always saw in Dean's eyes, especially when they were shining with the happiness that was more commonplace these days. Castiel loved Dean's happy green shade.
Hell, Castiel loved everything about Dean, shortcomings included.
