How does the expanding universe effect the Red Shift???

The galaxies are not accelerating away from each other by their own
force. The reality is the space between them is inflating,and that gives
the illusion they are blowing apart. Has to be very tricky to measure
the increase distance space is increasing between the galaxies(trying to
make a measurement relative to what?) The Doppler effect is
our measuring stick. How much redder is more reddening? Are we going to
end up with a red face(blushing) if we don't factor in space inflation
that is going on at a faster,and faster rate? Bert PS wish I knew
how fast the universe is expanding at this exact spacetime.
