In UK atheists considred more moral than theists.

Meh, colors are a phenomenon of consciousness. They are a construct. Suggesting that a color cannot be detected because there is not a construct available to consciousness is simply conflating multiple meanings of the word color. Color is a side effect of light being perceived and processed by a brain. So whether one can name a specific color or a new primary color is irrelevant because measuring the properties of light does not require the participation of biology and consciousness at that level. That we can detect infrared light makes it clear that we can detect things that there is no conscious construct for. The devices we use to detect such properties of light are themselves based upon things that we can observe and lead us to deduce the existence of infrared light. I don't know what the original point was, but this nonsense about a new primary color seems nothing more than a red herring. No, there is no construct in consciousness which corresponds to a new primary color or infrared light. That doesn't mean we can't detect "color" (strictly speaking, we can't, because it's a feature of consciousness; I rather doubt that fact is relevant to whatever the original point was).
