System

Here are the different staps and principle that lead the system.

V 0.1 - ALPHA

OSCS

Applications identified

We have identified the different types of UI elements where color should be applied :

Surface (Backgrounds)

Borders

Shapes (icons/elements)

Texts

Then the different states needed

Surface

Default + Hover

Borders

Default + Hover

Shapes

Default + Hover + Active

Texts

Default + Hover + Active

And finally categories

Primaries

You’ll define your own depending on your brand or interface considérations.

Semantics

Used in a lot of cases. We preferred to name all the colors by they HUE because red could mean danger but also busy, etc. Please check the great matrix example made by Atlassian Design Team here →

Accents

For a lot of different cases : tags, differentiation, etc.

Neutrals

They got a different scale because of the specific use and rules.

Handpicked colors

We’ve selected colors we loved, and this is a really tricky and subjective act.  

Some are directly inspired by Radix UI Colors which is also a great resource for your systems.
