== Background/Goal
Our system needs to document the different allowed degrees of opacity.
Once defined, the system's opacity values will be documented as tokens, which will ensure the application of system-compliant opacities in various contexts.
=== User stories
As a designer, I need to have access to the system's opacity values, so I'm aware of which level of opacity I can apply when creating system compliant designs.
=== Acceptance criteria (or Done)
[-] The system's opacity values are documented
[x] The tokens are 1:1 represented in #Codex
=== To do
**Design**
[-] Define global opacities values (choice)
[-] Define opacities nomenclature
[-] Define the overlay opacity https://phabricator.wikimedia.org/T299212
[-] Define the opacities decision tokens
[ ] Add the new styles in our [[ https://www.figma.com/file/2Jb1lVkhEMDFxO20I5xwyA/%E2%9D%96-WikimediaUI-%E2%80%93-Components-library?node-id=4%3A2425 | WikimediaUI-components ]] system file
