I need to make a Ram's jersey for a cake and I don't know how to get the navy colour on the jersey. Any suggestion??

Thanks

yes! i had to do the same thing for school letters. i used royal blue and orange. the orange dulls the blue. just play with it... you'll get the right color i'm sure

Assuming you mean the St. Louis Rams, I would start with a royal blue, then add a bit of purple and a bit of black until you get your desired shade. Remember that it will most likely darken as it sits.
