At least according to the site below. They posted a story today citing an "extremely reliable source" who confirmed that the new uniforms will be a throwback to the old orange and navy blue, but modernized and stripped down. It supposedly includes a modernized version of the old H logo and no shooting star. More details at the link below.
I'm not really a fan of the old colors. I was hoping for something new, with the new era in Astros baseball, instead of a throwback to the past.
