Hi, seeing these colours that makes our brain a bit confused, have you noticed that you choose red and blue both are primary colours. Normally I would expect a third primary like yellow, but you choose green which is a secondary colour of yellow and blue, so you have hidden yellow into green. Was it intention?

If I had to choose colour, I probably do take two primary like red and blue and then a secondary from mix of them like purple :)

I can understand your wife :)
