Kind of hard to find what you're looking for, there's this https://youtu.be/c4pXYHFtLQ4

This image is 500 pixels by 300 pixels, meaning it is made up of 150,000 pixels.

If you take the average of all 150,000 pixels the resultant color is R:120 G:164 B:127 (a desaturated green).

How could you possibly give me this exact color by only measuring a small subset of pixels? Say you took 50,000 measurements, surely you would still be off by a few hues or shades.

This same principle applies to claims of global climate change. How could you possibly assert a global increase of 1 or 2°C by measuring a few thousand points on a 510.1 million km2 sphere?
