Arthur smiles and gets some food 

Jacob looks at Arthur " hey Arthur what color is lighting actually "

Arthur thinks" it depends if usually looks purple from precipitation but if there's a lot of dust it's yellow and if there is heavy rainfall it can even look red but it's pure form without anything affecting the color is white "

Jacob nods " ahh ok " 'hmm so would his eyes would probably take the color of pure lighting or the purple' he thinks to himself [b]most likely purple as he is a son of Jupiter and I've seen Jupiter's eyes and they're pure white[/b] ' ahh ok'
