Red is one of the primary colors of the RGB color system - the other two being green and blue. To produce pure red in this model, one needs to keep it at the maximum brightness and saturation and lower the other two colors to zero.
The RGB and hexadecimal codes are (255, 0, 0) and #FF0000, respectively. Included in the X11 and later the web color list, the color can be used with its name, "red", in both HTML and CSS code.
The complement of Red is Aqua with the hex code #00FFFF. Complementary colors are those found at the opposite ends of the color wheel. Thus, as per the RGB system, the best contrast to #FF0000 color is offered by #00FFFF. The complementary color palette is easiest to use and work with. Studies have shown that contrasting color palette is the best way to grab a viewer's attention.
The analogous colors of Red (#FF0000) are Orange (Color Wheel) (#FF8000) and Bright Pink (#FF0080). In the RGB color wheel, these two analogous colors occur to the right and left of Red with a 30° separation on either side. An analogous color palette is extremely soothing to the eyes and works wonders if your main color is soft or pastel.
As per the RGB color wheel, the split-complementary colors of Red (#FF0000) are #00FF80 (Guppie Green) and #0080FF (Azure). 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.
Red triadic color palette has three colors each of which is separated by 120° in the RGB wheel. Thus, #00FF00 (Electric Green) and #0000FF (Blue) along with #FF0000 create a stunning and beautiful triadic palette with the maximum variation in hue and, therefore, offering the best possible contrast when taken together.
The tetradic palette of Red has four colors - #00FF00 (Electric Green), #00FFFF (Aqua) and #FF00FF (Fuchsia) in addition to the base color (#FF0000). 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.
Red square color palette has #80FF00 (Chartreuse (Web)), #00FFFF (Aqua) and #8000FF (Violet (Color Wheel)). 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.
Red Color Rainbow Palette
Our Red 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.
