I'm with you Peanut, bluebells are not blue, and the only blue flowers I have are light blue forget-me-nots. Take a walk in the woods at this time of year and compare the bluebells to the flowers of green alkanet, which are not only a lovely true blue but look more so compared to the purple bluebells around them.
A very good book on colour and its' uses is 'Colour for adventurous gardeners' by the late Christopher Lloyd.
to quote Christopher Lloyd, 'more then half the flowers described as blue in seed lists plant catalogues are some shade of mauve or purple'...'more than any other colour, blue needs contrast near to it, to prevent it looking dull'.
