I don't think I have a favourite color, I used to say that blue was my favourite color when I was younger, but I don' think it is today.
I would rather talk about my favourite color combinations, most colors can look good if they are combined with other colors in a good way.
If I would have to list some nice color combinations, golden and red/yellow/orange colors fits extremely nice, and combinations of dark green, light green and brown are usually good too.
