Modes and harmonies

A palette window is always in one of eight modes, chosen from the header menu. Seven work out a harmony from one or two seed colours. The eighth is a palette of your own.

Blend space

Ramps and monochromatic scales step through sRGB or OKLab. OKLab spaces the steps so they look evener to the eye. The setting belongs to the window, so two windows can differ.

What any harmony colour offers

Open its detail to read its values, copy it in any format, tear it off into its own card, send it to the Bench, promote it to First or Last, or add it to a palette. ⇧⌘A adds the whole harmony at once.

Only the seeds are yours to edit

In a harmony, the editor opens on the seeds and nothing else. Every other colour is worked out from them, which is what a harmony is, so there’s nothing to edit in a derived colour that moving its seed would not undo.

If you want one of the derived colours but not quite as it came, add it to a palette and edit it there. In Palette mode every colour is editable, because every colour is one you put there. A harmony is a calculation you steer by its seeds. A palette is a list you own outright.
