According to wallabyguy, Saffron was only brought back as an option in '08 overseas, not available in the states. Solar's still the only one here.
To my eye, the only time they really look different from 20 ft is in bright sunlight, in which case the flake in the solar make the yellow appear a lighter shade. Saffron's my favorite color, but after seeing more solar in person, the flake is subtle enough they're both fabulous to my eye!
