What color are Crona's eyes?

Excuse me, I was wondering if you could clarify something for me. In the context of the topic we're discussing, there's a mention of Crona. Now, I'm not sure if this is related to the financial or cryptocurrency world specifically, but I'm intrigued. Could you tell me, what color are Crona's eyes? I understand this may seem like an odd question, but I'm genuinely curious and it's been bugging me. Perhaps there's some significance to this detail that I'm missing. Thank you for your time and assistance.
