Inkscape should have a very robust "color selector"
(not the general purpose type) that deals with color
theory and color related issues that novice and experts
alike could benefit from. Essentially a utility that
lets you choose a color and see matching,
complimentary, or harmonious colors (and other
important color theory related "issues" that
non-designers aren't always so aware of). We can't
forget color mixing either. ;)
A great example of what I am talking about is what the
program "Color Schemer" does. You can try a "basic"
version of it online at

Another great feature for this to have would be to
quickly generate swatch libraries for you from directly
within that dialog.

Great Idea!!! Inkscape would become attractive to professional
designers with a function like that!!
