It is interesting that more colours are not present in Sindarin, such as purple or pink, I found a really interesting article about why that may be. There are more colours for types of red and brown and sky-blue but sadly not the colours for me to post a rainbow. The colours in the screenshots are so gorgeous. I have edited them slightly so they have a more similar level of saturation but not by very much at all (the blue is unedited).
