Cristian Romero has created a free digital tool for analyzing color schemes. All you have to do is drag a "jpg," "png," or "bmp" into a box, and it will output a gamut map. The gamut map shows which colors are inside the color scheme and which are outside.
Here is a painting by Anders Zorn, showing the narrow range of colors used in the picture. The scheme is centered in yellows and oranges. The "extra-gamut" colors (colors that don't appear in the scheme) are magenta, blue, cyan, and green.
This image has a wider gamut, extending across neutral gray at the center of the circle. It has full intensity yellows and reds as well as some cyan, green, and violet. The gamut doesn't reach all the way to the outer edges of the circle because some hues are only partially saturated.
Here's a fine example of a complementary gamut, a narrow slice of the color wheel from orange to cyan-blue.
The gamut mapping idea is useful both for analyzing color schemes, as we see here, but also for generating the color schemes that you want for your picture.
