Have you printed out the image? Screens can't display all color. Have you
looked at the image at 100% magnification on the computer screen? Screens
have only around 100ppi. Don't know if there are screens at 300ppi.

actually it's silly for us to expect to reproduce these colours anything
approaching accuracy since they're not colours in th true sense (anyone
remember that old polaroid positive film that allegedly created colours by
diffraction?*) - the gamut is way out of the range of screen and print
(most metallic colours are), but all of us that have experienced these types
of images of feathers and insect fuzz have generally found film could
capture colours closer to our perception than digital often has been able to
do.

actually here's something I've just thought of which wont solve the colour
issue but could be interesting, stereo pictures of this type of iridescence
might look a lot more realistic, as part of the sheen we see is from
observing the diffraction generated colours from two separate points of
view - one for each eye. being slightly out of phase creates the shimmer -
stereo should capture that effect and give us a much more acceptable image
