The Colours block
Show your palette and let readers copy exact values.
Updated 29 September 2026
Add up to 24 colours. For each colour set:
a name and the HEX value (or use the colour picker) — RGB is worked out from it
CMYK for print, for example 0 60 80 10 (it's saved as C0 M60 Y80 K10)
a Pantone reference, for example 3435 C (saved as PMS 3435 C)
an optional usage note, such as "Headlines and buttons"
You can also add colours straight from the brand's settings, so the values match everywhere.
CMYK: type it or calculate it
Click Calculate next to the CMYK field — or Calculate CMYK for colours without one — to fill in a value based on the HEX colour.
Pantone references can't be calculated; type them in from your Pantone guide.
Options
Click to copy values — readers click a swatch to copy the HEX value, or click any value (HEX, RGB, CMYK, Pantone) to copy exactly that.
Show RGB, Show CMYK and Show Pantone — choose which values readers see. CMYK and Pantone only appear for colours that have them.
Layout: 2 columns, 4 columns or List.
