Astroron's comments on my image , in the other General forum thread, (#64 &67), showing the orange SN in NGC5128 led me to believe it was due to 'dust' in the gas cloud in the galaxy, what is called 'extinction' I believe, as we see in some sunsets on earth. It is good to see more orange images emerging. I don't know if we can make assumptions about the star type without more information, including how the colour changes as the SN fades.
