Open Shades of Green| Format | Looks like | Use it for |
|---|---|---|
| HEX | #3A6EA5 |
Anything on the web — CSS, HTML, design tools, Slack and brand tokens. It is the format designers and developers both understand. |
| RGB | 58, 110, 165 |
Screens: image editors, canvas code, display settings, anything that mixes light. Each channel runs 0–255. |
| CMYK | 65, 33, 0, 35 |
Print: ink coverage on a press. Ask for it when a printer requests CMYK values, and expect them to be adjusted to the actual press profile. |
HEX and RGB are two spellings of the same thing — both describe light on a screen, and converting between them is exact. CMYK is different: it describes ink, and the conversion depends on the paper, the press and the colour profile. The numbers here are a plain mathematical conversion, not a colour-managed one.
Both tools run entirely in your browser. Nothing you type or pick is sent anywhere, which is the main reason they exist — the popular alternatives are usually behind a sign-up.
#3A6EA5 is base-16
shorthand for red 58, green 110, blue 165 — the same colour as
rgb(58, 110, 165). Converting between them is exact, which is why the
picker can update both fields as you type.
#RRGGBBAA value is not understood. If
you need rgba(), take the RGB values from the picker and add the alpha
yourself.
