Gasoline Color.

[DMCVegas@xxxx]

I know that companies dye the gasoline that goes into cars, but is 
there a specific color that it should be respective to octane? A 
couple of month's back when I first opened up my gas tank, I had 
Chevron 92 in the tank. I noticed that the gas was tinted blue. 
Saturday moring my fuel pickup hose broke (my fault. I tightened a 
hose clamp way to tight, and it cut the rubber). The day before I 
filled up with 92 octane from a Wal Mart gas station. When I opened 
the tank, the fuel was yellow.

Is the color of the fuel an industry standard, or is it just by whom 
ever distills the fuel? Because I know that all tax-exempt diesel for 
agricultural use is supposed to be red for example.

I just want to make sure that I didn't get jiped when I filled up 
with the higer grade, or at least what I thought was higher grade 
fuel.
