Differences In Paint Colors/Southern Pacific Red

[Eaglecliff]

Been to Pendon, worth the trip. Grew up on John Aherne. Back to the question - how do we know that the colour I see is the same as what you see?

 

[Greg Elmassian]

If you are asking if there is a way to measure the color, there is, calibrated cameras and software...

how do we know that the colour I see is the same as what you see?

That raises the question of how do I know that the colour I see is the same as what I see?

Nonsense question, you say?

Tested sense, actually.

When doing those cover one eye tests, one of my eyes sees things a little greener & the other sees things a little redder.

Amusingly it is on the same sides as navigation lights.

 

[Greg Elmassian]

Yes, now you are asking a different question... no, not all eyes are the same, and how do we know if the blue you see is the blue I see...

Now back to the statistics of color blindness in men, 20% of men have some type of color blindness, and the most common is red green...

I leave it to you to derail you topic further ha ha!
