NOT Runway Red anymore

This colour is called London Luxe or Runway Red - it says both on the package.
I have been using this exact brand/colour for a few years now, and it always had BRIGHT BRIGHT red results.
However, the last couple times I used it, it turned my hair darker red, like a cherry colour similar to Feria R57. It looks okay, but is NOT the same formula as it used to be.
My dad called it Fire Engine Red before and now he couldn't tell I used the same one.
