Solo is beautiful whatever solo may be! I have only hatched white silkies. So i couldnt tell you what color solo is but its a beautiful color. Sexing with silkies is really hard I also go with the comb sizing From learning the roosters will have very broad combs and will begin to change from a black/blueish color to a dark mulberry/black color with hens they are smaller no broad and kinda stay a dark black/blue color. Sorry I can't be more of help I have hard enough time sexing my own..LOL
