Sol's Colour?

(My curiosity was piqued also not so long ago,and on the Coronado forum enquired as to the anomalous orange hued colouring of pretty much all their sun images,when the sun,plainly,is a lustrous scarlet visually.Greg Piepol replied that it was simply a matter of aesthetics and convention more or less.
I don't recall if I asked how such a convention developed,nor did I pursue the aesthetics question.
The orange colour is not an inescapable consequence of post processing,it can be any colour the processer desires.
It would be interesting to see a decently presented side by side comparison maybe.)

...I just pasted in a reply I made to a question about PST colouring in another forum on here.
I think I'm right on the basic facts I hope.
Still,would anybody care to bother creating a comparison? 8O

Hi Bruce -

It's an interesting question. Since H-Alpha imaging is monochromatic in the red, the decision to balance the color towards yellow/orange is an aesthetic convention - maybe because we've seen and known the sun as yellow since our first set of crayola crayons? Our eyes are not too sensitive to things at the deep red end of the spectrum. My personal preference is often for grayscale H-Alpha images (until I see one of Greg's spectacular orange ones!). Here is a prominence close-up from yesterday - I made the decision to apply a subtle tone to the original grayscale - played around with many different tints and wound up with... yellow/orange.
