true colours

I stumbled across this some time ago, don't remember when. But I wanted to share it as it is the most realistic presentation of star colour I have seen in the classic Hertzsprung-Russell Diagram.

HR Diagram with realistic star colours

The blues and oranges are pale. The colours are subtle. And this is how we see the colours of stars in the telescope. Or in photographs that are not oversatured.

From Bruce MacEvoy's web page Astronomical Files from Black Oak Observatory. Such as amazing resource.
