Blue Mark (Water) Spots on Garage Floor Front Passenger Side

[Georg300]

Right now is pretty hot in the Sacramento, CA area. Recently I have discovered big area spots of water with blue "outlines", you know, blue water spots. I am aware that both Radiator and Windshield fluids are blue. None of them are below minimum level, radiator level is perfect.

Also judging by the amount of water, if there was a leak on my windshield reservoir, I think it would be empty by now, which is not.

Question is, can the condensation fluid from the A/C system ever leave blue (outline) spots? I want to believe this leak is from the winshield (fluid reservoir) but I could not find anything.

Any thoughts?
