According to internationally accepted modern periodic deskArsenic is as with mass no 75 and atomic number 33.It has 5 electrons 9elements from four th period onward have a maximum of 18 electrons so i'm not sure about valence electrons) neon or ne is a noble gas.It has inert fuel properties.It's referred to as happy given that it has end up stable so it does no longer must bear any longer reactions.
I think your question is a bit ambiguous since you haven't defined what you need the colours for (the product, outcome) Based on the yarn, I'm just assuming your knitting something for Winter and so I would say that those colours do not match (for a scarf or mitten, or tuque of some kind)Like it said it really depends on what your using them for, for a war propaganda poster, I suppose its fineHOWEVER, If you simply mean generally, then I would say they dont, the gree, yellow, and black match, the the indigo/violet is out of placeI would suggest getting a slightly more prominent violet colour, a slightly brighter yellow, and a more neutralised green (closer to pea colour) So that is my opinion on the colours but I wish you luck in whatever your trying to achieve D
