On the Colour Details page for any colour, you can find the "Combinations tab". This presents you with a list of possible combination colours, based on different similarity properties such as nuance similarity, hue similarity, chromaticness similarity and others. You can also filter the combinations for specific hues and nuances based on your selection of similarity.

By clicking on a suggested combination, you can compare the selected colour with the combination colour to make a visual assessment of the combination.
