Description:
This star lies in a field rich of stars, but clearly stands out of the crowd with its faint orange dominated whiteish colour. OK, I agree that its colour is unimaginable based on this definition, so I guess you will have to see it yourself. Quite difficult object thanks to its field and faintness.
