Colors and brand roles

Add colors, tune them by hex or HSL, pull colors from a photo, and give colors brand roles.

Each color in the palette has its own card: a big swatch, a name, a hex value, a role, HSL sliders and a spec.

Add colors #

  • + Color, in the toolbar or at the end of the swatches, adds a new color.
  • From a photo… picks a handful of colors out of a material board or site photo and adds them to the palette. The photo is processed on your computer. It's never uploaded and never saved; only the colors are kept.

Change a color #

On the card:

  • Type a name in the name box.
  • Type a hex value, like #2563eb, and press Enter.
  • Click the small color box to use your browser's color picker.
  • Click ⌖ to pick a color from anywhere on your screen. It shows only in browsers that support it.
  • Drag the H, S and L sliders to adjust hue, saturation and lightness.

Under the sliders, the card shows the color's RGB values and an approximate LRV. That LRV is a screen estimate from the hex. Use the manufacturer's published LRV for specification; see Finish schedule and export.

Click the big swatch to copy its hex value.

Give a color a brand role #

Pick a role in the card's role list: primary, accent, background, surface or text. Pick no role for a plain swatch.

A role belongs to one color at a time. Giving a role to a color takes it off whichever color had it before.

Once any color has a role, the brand preview appears above the swatches. See Contrast checks.

Reorder, copy or remove a color #

At the bottom of each card:

  • ◀ and ▶ move the color earlier or later. The order is the palette's order, in the schedule and every export.
  • The copy button duplicates the color. The copy keeps the spec but not the schedule tag or the role.
  • × removes it.
