Left to right: 4X Open Road purchased about two years ago; 4X Cowboy hat purchased about 25 years ago, trimmed and reshaped; brand new Stratoliner - no Xs.
The OR and Strat are very close in color, but the Strat has a little more rose to it. I don't know if the hybrid's color has changed with 25 years of wear/weather/brushing, but it's obviously very different. As one might expect, all three change color fairly dramatically depending on their surroundings and the light temperature.
So far, I'm very happy with the Strat; it's what I was hoping for when I bought the OR, which is so stiff I've been reluctant to reshape it. I'm lining up models for the Women in Men's Fedoras thread, so we can get a more scientific evaluation of the hat colors.
