Create complements in 3 easy steps

Color complements and harmonies
Step 1 of 3

Select from the list the type of input data you will insert.
Some color spaces (XYZ, CIE-L*ab for example) require to additionally select the proper illuminant (light condition) and observer (viewing angle). In case of RGB or CMYK data the default illuminant and observer (D65/2°) are automatically set.

Step 2 of 3

Insert your color data in the entry fields. Previously entered data will be inserted by default making easy to transfer the same data across the different tools of the site.
As an alternative to manually entering the color data, it is possible to pick a color previously saved.
The RESET button is available immediately below to clean all the entry fields and start a new insertion.

Step 3 of 3

Press the CREATE button to generate the desired complements.
The tool automatically checks for data consistency. In case an entered value is not compatible with the select color space an error will be displayed and the associated entry filed will be flagged with a red icon ().


As a result a large color swatch with the original color as background and containing the calculated complements, will be displayed. The original color and all complementary color swatches will be clearly identified by the corresponding sRGB values.



Clicking on any of the color swatches will open the "options" dialog, where additional choices are available for the selected color:

  • MATCH the selected color to commercial tints and popular fandecks.
  • CONVERT the selected color data to different standards.
  • SAVE the selected color for future use.
  • SAVE ALL the color results for future use.


Saved colors, if available, are displayed immediately below the entry fields. These colors can be used as an alternative to manually entering color data. To pick a saved color just click on it and the related values will be transferred to the entry fields automatically.
Positioning the mouse cursor on top of each color makes the color name or content to appear (this could not work on phones, tablets and touch screen devices).
