Does anyone know of a way to change / restrict the colours that are in the tinyMCE text colour picker? I have located a file in the /concrete/js/tiny_mce_309/themes/advanced/js/color_picker.js

also noticed it was in two places including:
/concrete/js/tiny_mce_309/themes/concrete/js/color_picker.js

It lists the colours however when I change them I still get the same pallete in the tinyMCE editor???

please tell me someone has done this and can point me in the right direction
cheers
