Navy. For as long as I can remember. I didn't know anyone else who said navy was their fave. When I connected with old friends on Facebook ten or so years ago one woman said I bet you still love navy blue. :)
I didn't always like Navy ... but recently I changed my mind. It can look very classy and crisp ... and it's fun accessorizing it with different colors.
I like yellow, and I think I like it because it's a bright cheerful colour. I love yellow flowers and one of my absolute favourites is yellow - Welsh poppy.
I'm not sure. Green has been my favorite color for a long time. I think I began to appreciate it more as I became more interested in gardening, though.
