Extension Knowledge:

Line color is the choice of any number of pigments that suit the display. Sometimes a sheen or gloss is used as well as color to set the contour lines apart from the base map. Line colour can be varied to show other information. In the case where the data represented by the lines are the primary subject of the map, shading called layer tints, which is the use of hue between different isarithmic lines, is often added to make the map easier to read. However when elevation contours are used, the method is called hypsometric tints. The options for layer tints are lightness (tonal value) with darker shades representing greater amounts; double-ended; and spectral sequences. This uses can be appreaciated on temperature as well as elevation maps.

After you get specific line color and fill color set between paths, please start to convert raster image to vector image through software, and then, this conversion could be processed quickly. And later, vector image with specific line color can display in destination folder.
