World's simplest online tetradic color palette generator. Just select the primary color for the palette on the color wheel, and the tool will instantly create a contrasting four-color scheme. You can interactively adjust the positions of the corners of the colors forming the rectangular pattern on the wheel, modify the palette's brightness and translucency, and choose the color format (HEX, RGB, HSV, CMYK, LAB, and more). Free, quick, and very powerful. Press a button – get a four-color set. Created with love by team Browserling.

This browser-based tool creates a palette of four evenly spaced shades around the color wheel, known as tetradic colors. A tetradic color scheme, often also called a rectangular or double-complementary scheme, is formed from two opposite pairs of complementary colors arranged in a rectangular shape on the wheel, offering strong contrast. These four shades are very different, yet they combine well with each other. Once you select the base color on the color wheel (or specify it in the options), the program automatically calculates the next three shades. The second color is a direct complement to the selected color, while the third and fourth colors are shifted by 90° on the color wheel, creating a second pair of complementary colors. All four shades have the same brightness and translucency, which can be adjusted using the interactive on-screen sliders next to the wheel or by entering precise percentage values in the options. For brightness, the percentage value of 0% means "no light", so it's the black color, and the percentage value of 100% means "maximum light", so it's the white color. The optimal value for brightness is 50%, which shows the color in its pure form, not too dark or too light. For translucency, the percentage value of 0% means "fully translucent", so the color becomes fully see-through, and the percentage value of 100% means "no translucency", so the color becomes fully opaque. You can also customize the output format of the color swatches and modify the palette before saving it. Specifically, you can apply subtle outlines to each individual swatch and add labels with color codes on top of them. The tool supports more than 10 different color formats, such as Hex, RGB, HSL, HSV, LAB, LUV, CMYK, YIQ, XYZ, and more. For saving, you can choose to download just the four-color palette in PNG format or a full copy of the tool's window, including the color wheel and the four markers of the four colors. Fun fact: All four colors form not just a rectangle but a perfect square on the hue circle (360° / 4 = 90°). For this reason, color theorists sometimes refer to it as a square tetrad. Png-abulous!

In this example, we generate a high-contrast, fully saturated four-color scheme. The palette starts from a pure "Blue" hue, which we enter in the tool options. The tool instantly computes its hue angle (240°) on the HSL color wheel and identifies its direct complement, "Yellow", across the wheel (hue angle is 60°). Then it locates the second complementary pair: "DeepPink" and "SpringGreen" (330° and 150°). As you can see, all these colors are shifted by 90 degrees on the color wheel from the first color (60°, 150°, 240°, 330°). Additionally, we print the English names on the colors and keep them fully opaque so that they don't lose their saturation.
This example creates a slightly lighter, softer, and more delicate square tetrad palette. By setting the overall HSL lightness (L) value to 66%, the colors appear softer while still maintaining their contrast. The palette originates from the "Coral" color, and all four hues are precisely positioned at 90-degree intervals on the color wheel, forming the characteristic square scheme. Colors are displayed in hexadecimal format, and the download format is set to "Palette as a PNG", which creates a high-resolution PNG palette, suitable for use in other graphics editors and design tools.
In this example, we explore a moody tetradic color scheme with the first color set to "Navy". The brightness slider is lowered to just 25%, producing deep, shadowy hues. At the same time, we reduce the translucency to 50%, giving the entire palette a see-through effect. Since these darker, semi-transparent tones can blend (especially when viewed on a dark background), we add separators in the form of 1-pixel outlines around each color block. The result is a dark palette, rendered in the extended HSL color space with the alpha channel as the fourth parameter (sometimes called HSLA color space).
