Before vectorizing a color image to color vectors you need to reduce the colors on the image.

After you have done this you can vectorize the image using either of two methods:

Color Layers method

Vector Colors to Raster Colors method

If you have been unable to reduce the colors on the image cleanly, vectorize the image using the Vector Colors to Raster Colors method. Otherwise, use the Color Layers method.

The Color Layers method is better because:

It uses color information during vectorization and therefore produces better vectorization results.

It gives you the option to convert one, some or all the colors in the raster image. Using the Vector Colors to Raster Colors method, all colors are converted.

Color Layers method

In this method you select a Pick Color or Select Color Layers. Scan2CAD converts the colors you have selected into color vectors.

Raster image	Vector image: no Pick Color, no Layer Colors

If no Pick Color or Layer Colors are selected, Scan2CAD is “color blind”. It vectorizes the color image as though all the colors were black.

Raster image	Vector image: Pick Color = blue

If a Pick Color is selected, Scan2CAD only sees and vectorizes Pick Colored parts of the raster image.

Raster image	Vector image – Layer Colors = blue, brown

If Layer Colors are selected, Scan2CAD only sees and vectorizes Layer Colored parts of the raster image.

If Layer Colors are selected, any Pick Color is ignored.

Vector Colors to Raster Colors method

In this method you vectorize the image as though it was a black and white image. After vectorization you use Vector Colors to Raster Colors to assign colors to the vectors. Each vector is assigned the color that is dominant in the raster image beneath it.
