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 and logo.svg.

Correct use

Recolouring the mark

Stretching or changing the proportions

Shadows or glow

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.
