Coolant color?

Obviously...no. Hard to tell for sure from the picture, but it looks like some corrosion. Worst case is a previous owner put some stop-leak additive in.
I'd drain and flush the system first chance you get. If it's your first time don't forget the block drain in the center iron under the spark plugs. Supposedly any ethylene glycol is OK, but lately I've been using the FL-22 coolant. Comes from different manufacturers and labeled as for "Asian Vehicles"...low on silicates and borates. Do no more than 50/50 mix. Coolant can go acidic over time, and a lot of electrolysis from the bi-metal engine. That's hard on soft seals. Personally I change coolant annually, usually as part of a maintenance routine when it comes out of winter storage here in the Midwest.
