      The issue can be reproduced with a simple Qt Quick application:

      import QtQuick 2.9
      import QtQuick.Window 2.2
      
      Window {
          visible: true
          width: 640
          height: 480
          color: "#353637"
      }
      

      And an even simpler C++ GUI application:

      #include <QGuiApplication>
      #include <QColor>
      #include <QDebug>
      
      int main(int argc, char *argv[])
      {
          QGuiApplication app(argc, argv);
      
          qDebug() << QColor("#353637");
      
          return 0;
      }
      

      The disassembly (the debugger is pointing to 0xa4a9ddba):
