RAL is a standardized proprietary color system used to identify specific colors for industry use, usually for varnish or powder coating metal. Many of the colors are based on reflectivity or translucency, so the options displayed will not have all the attributes they would have with a RAL color set.

Complementary colors are pairs of colors which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale color like white or black. When placed next to each other, they create the strongest contrast for those two colors. Complementary colors may also be called "opposite colors." Wikipedia
Analogous colors are groups of three colors that are next to each other on the color wheel, sharing a common color, with one being the dominant color, which tends to be a primary or secondary color, and a tertiary. Wikipedia
The triadic color scheme uses three colors equally spaced around the color wheel. Triadic color schemes tend to be quite vibrant, even when using pale or unsaturated versions of hues, offers a higher degree of contrast while at the same time retains the color harmony. Wikipedia
Split Complementary color is a mix between Complementary color and Analagous color. It forms a modified triangle where one color is dominant and the other two make great accents.
Tetradic (Rectangular) Color
The tetradic (double complementary) colors scheme is the richest of all the schemes because it uses four colors arranged into two complementary color pairs. This scheme is hard to harmonize and requires a color to be dominant or subdue the colors; if all four colors are used in equal amounts, the scheme may look unbalanced.
The rectangle color scheme uses four colors arranged into two complementary pairs and offers plenty of possibilities for variation. Rectangle color schemes work best when one color is dominant. Wikipedia
Tetradic (Square) Color
The square color scheme is similar to the rectangle, but with all four colors spaced evenly around the color circle. Square color schemes work best when all colors are evenly balanced. Wikipedia
