Hi Bob, Yes, after I made that remark I looked it up (should have looked it up BEFORE!) and I saw that there are several possible colors depending on octane. I was going by my experience of flying (once) in a Cessna 152. The instructor and I went through a thorough pre-flight and part of that was to check for water and other contamination in the fuel at several points in the fuel system. I recall the fuel being light blue.
