What is an easy way to create a color scheme using an elliptical path and a Munsell conversion program?
I assume you mean an elliptical path through the color space to select the colors in your scheme. An easy way would be to draw (either by hand or electronically) the polar coordinates of the Munsell system and then select the range of hues, etc you want to traverse and simply sketch out the path. There is no need to have a precise ellipse. You can then select the Munsell notation that your path crosses and use the conversion program to convert those over to RGB, CMYK, or whatever other coordinates you would prefer to work in.
