A split-complementary color palette consists of the main color along with those on either side (30°) of the complementary color. Based on our research, usage of split-complementary palettes is on the rise online, especially in graphics and web sites designs. It may be because it is not as contrasting as the complementary color palette and, hence, results in a combination which is pleasant to the eyes.
Triadic Palette
Cobalt Blue triadic color palette has three colors each of which is separated by 120° in the RGB wheel. Thus, #AB0047 (Rose Garnet) and #47AB00 (Kelly Green) along with #0047AB create a stunning and beautiful triadic palette with the maximum variation in hue and, therefore, offering the best possible contrast when taken together.
Tetradic Palette
The tetradic palette of Cobalt Blue has four colors - #AB0047 (Rose Garnet), #AB6400 (Windsor Tan) and #00AB64 (GO Green) in addition to the base color (#0047AB). A tetradic color palette is complex and, in most cases, should not be used off-the-shelf. We suggest tweaking the colors slightly to achieve desired results.
Square Palette
Cobalt Blue square color palette has #AB009D (Heliotrope Magenta), #AB6400 (Windsor Tan) and #00AB0F (Islamic Green). Quite like triadic, the hues in a square palette are at the maximum distance from each other, which is 90°.
Note: For several colors purposes, a square palette may look much better than the tetrad color palette.
Cobalt Blue Color Rainbow Palette
Our Cobalt Blue rainbow color palette is based on the RGB model and consists of 7 colors, just like the traditional rainbow. You might not see a lot of variation in color, especially if the chosen color is dark or extremely light. However, this can lead interesting rainbow palettes that are faded, soft, pastel or dull.
