Ive just realised I’ve held a full UK driving licence for sixty years next April, time to give it up I’m thinking.

Richard Of York Gave Battle In Vain. Always puzzled me, with my wonky colour vision, why blue got a whole three letters. Violet and Indigo are just kinds of blue. (Well they are to me) Yet there are a load of different kinds of reds and greens and they don't get their own letters.

No point telling me I'm wrong. I won't understand, because of my poor colour vision.
I too have poor colour vision but when you consider that the labels are just that, labels for particular frequencies of electromagnetic spectrum. Having recently had the lounge redecorated I'm currently looking at our coconut coloured walls and Angel Wings coloured feature wall. ( Tikurilla, Norwegian paint manufacturer ) colour chart.

Colours can be subjective

Have I already mentions that the number in the rainbow is due to superstitions from the person who first published about it
he was convinced that there need to be 7 as 7 is a magical number

hence he put Indigo in as well as blue

so really he only considered that there were 6

or so I heard

This sent me off reading. This is interesting https://www.thecolumbiasciencereview.com/blog/newton-and-the-science-of-color mentions Newton choosing seven colours.

Names of colours are more than just labels on the EM spectrum. Our red/green/ blue sensitivity is hard wired by cells in our eyes. So I imagine that if we had different eyes with four kinds of colour sensitive cells we could have four primary colours. Or two. Maybe. Or maybe I'm talking nonsense.
 
Having no style at all is just creating another style

It is Individualistic
and hence very on trend and fashionable
