He wrote an educational article covering key color concepts for programmers. He also proposed and created a new community documentation repository called color-and-hdr on freedesktop.org, which covers color and HDR topics beyond just Wayland — including EGL, Vulkan WSI, and DRM KMS — with the goal of making it a community-maintained resource. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the color-and-hdr repository on freedesktop.org and what does it cover? The color-and-hdr repository is a community documentation effort hosted at gitlab.freedesktop.org/pq/color-and-hdr, created to gather information about color management and HDR on Linux. It was split out from the Wayland CM&HDR protocol extension merge request to allow broader scope, covering not just Wayland but also EGL, Vulkan WSI, DRM KMS, and more. The goal is for it to eventually become community-owned. _Developers working on Linux display stacks track color-and-hdr ecosystem developments on daily.dev._ ## Similar posts on daily.dev - [Weston 16.0 Compositor Released With HDR Improvements, Vulkan Fixes](https://daily.dev/posts/weston-16-0-compositor-released-with-hdr-improvements-vulkan-fixes-l4sfjkkcj) · Phoronix · 0 upvotes · 0 comments - [Wayland's Weston 16 Alpha Brings HDR Improvements, Vulkan Renderer Fixes](https://daily.dev/posts/wayland-s-weston-16-alpha-brings-hdr-improvements-vulkan-renderer-fixes-bnkh3gomy) · Phoronix · 0 upvotes · 0 comments - [Color picking Oklch for mortals – Hugo Daniel](https://daily.dev/posts/color-picking-oklch-for-mortals-hugo-daniel-x8aaghqka) · Lobsters · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/a-pixel-s-color-new-documentation-repository-l63zyn3ma) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"A Pixel's Color & new documentation repository","url":"https://daily.dev/posts/a-pixel-s-color-new-documentation-repository-l63zyn3ma","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/a-pixel-s-color-new-documentation-repository-l63zyn3ma"},"datePublished":"2026-08-11T08:55:10.503Z","dateModified":"2026-08-11T09:26:09.317Z","description":"Collabora engineer Pekka Paalanen shares his journey learning color management concepts for Wayland and Weston HDR support, noting that color knowledge is...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ac05476ad3d834c4dc5a4bfcb9557060?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/ac05476ad3d834c4dc5a4bfcb9557060?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Collabora Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collabora Blog","logo":"https://media.daily.dev/image/upload/s--ZGZ0FjqS--/f_auto,q_auto/v1786438306/logos/collabora?_a=BAMAMicg0","url":"https://daily.dev/sources/collabora"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/a-pixel-s-color-new-documentation-repository-l63zyn3ma","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collabora Blog","item":"https://daily.dev/sources/collabora"},{"@type":"ListItem","position":3,"name":"A Pixel's Color & new documentation repository"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/a-pixel-s-color-new-documentation-repository-l63zyn3ma#faq","mainEntity":[{"@type":"Question","name":"What is the color-and-hdr repository on freedesktop.org and what does it cover?","acceptedAnswer":{"@type":"Answer","text":"The color-and-hdr repository is a community documentation effort hosted at gitlab.freedesktop.org/pq/color-and-hdr, created to gather information about color management and HDR on Linux.
