How many miles? The engine oil in mine is still light yellow after 2 weeks and 600 miles - you can hardly see it on the dipstick. The coolant is blue. The brake fluid is almost clear - slightly yellow. The transmission fluid is pinkish-red. The iVTM-4 fluid is pink. The transfer assembly oil is dark yellow. There is no power steering fluid, as stated. The washer fluid is clear. The refrigerant oil is clear. The refrigerant itself is a gas outside of the system. The struts have oil, but it wouldn't be leaking under the engine compartment. The only other fluid I can think of is in the motor mounts, but I don't know what color it is.
EDIT: See this thread about a leaking motor mount in a G1.
