More fun color maps / color scales

@sjr51 kindly shared code for Kovesi's perceptually uniform color maps here.  It's not that hard to click on these *.ibw waves and then choose them for a fun new color scale.   But why not have Igor 10 actually embed some of these improved, perceptually-uniform color scales? 

It would also be great to have a default option for transparency in color scales.  Again, not so hard to do manually (add a 4th column), but would be a nice feature for Igor 10.
