The navigation background color changes unexpectedly to a darker shade. It started after the update from Expo 51 to Expo 52

Expected behaviour

It should have lighter shades

How to reproduce?

It's hard to reproduce, because in Expo Go and Xcode, everything works normally

The problem was with the newest version of Expo 52/53. Here, iOS doesn't correctly read alpha colors. I need to use the tinycolors library to lighten the color and transform it to a hex string.
