Colour??

Am trying to design a vest top using our cotton ribbon,

Have already made one in the silk, need one of the girls to model it as the sleeves/straps are too long and it is very deep plunge, but they are drinking tea on the patio being useless as only elderly teenagers can be. I keep knitting the cotton one (should be dyeing, but stuck on the computer) I was making it for me, but I'm really not sure about the colours.

Guess if I don't like it I can knit another, trouble is I only have pale blue/green left which are not good colours for me to wear, I suppose I could break into the stock........
