I don't have the photo shop skills others have on here but I think this is going to be a red blasty jersey using only retro colors.
Something like this.
The logo probably isn't right as that's more difficult to guess as what they might do to recolor the logo, but I think the jersey will follow this pattern with it being mostly red, and then with the white and yellow striping at the bottom. If one of our more skilled graphic designers wants to give something like this a shot then that would be awesome.
No inside info here but just based on some tweets from Ryan Popowich about how "Red, Yellow, & White" are the Flames colors in regards to why we don't have a black jersey, and based on some of the leaks of other teams having their jerseys re-done in the current colorways makes me think this will be a retro colored Blasty jersey.
