This doesn't work for galaxies. You must get absolute magnitude from a database observed from real telescopes and recorded on the gettysburg software. Then you can calculate distance, and the velocity using the Red Shift as it moves away from our sun. Next use a complicated spreadsheet with some formula. And, how accurate is this? Here is the formula, next comment:

Check 1:59. IMHO it is not correct to say that "object that is further away, has different light spectrum (or color)", because it only has less light intensity. Frequency of light is not changing over distances, or is it?
I guess Hertzsprung Russell diagrams has something to do with hypothesis, that universe is expanding at accelerated speed, but I'm not sure. What are your thought about it?

It was an attempt at gentle irony. Is it too subtle?
