The mark is the **KYE™ monogram**: the three letters K, Y and E on a rounded indigo-violet square, over the kit's **rail and nodes** (rail grey, then white). The rail stands for the governed path every action takes: identity, authority, evidence. The SVG masters are [mark.svg](https://kyeprotocol.com/brand/mark.svg) and [logo.svg](https://kyeprotocol.com/brand/logo.svg).

Correct use

Recolouring the mark

Stretching or changing the proportions

Shadows or glow

**Do**

- Write the name as KYE Protocol™, and the short form as KYE™.
- Keep the rail and its nodes as part of the mark.
- Keep the logo flat, with no effects.
- Respect the clear space and minimum sizes.
- Use the 16-pixel drawing for favicons.

**Don't**

- Use the letter K alone as the mark.
- Add nodes to the rail or change its colours.
- Put gradients, shadows or glow on the logo.
- Use robot, sparkle or brain imagery next to it.
- Imply that a customer, regulator or certifier endorses the brand.

Notifications look the same in every product: a round node in the status colour, a short title, a one-sentence message, at most two actions and a time rail at the bottom. Hover to pause the timer; on a phone, swipe it away.
