Good point! For the umbrella of HDR features (of which this is one of a handful of features that will ship independently), we had filed https://github.com/mozilla/standards-positions/issues/1359
But it's a good idea to file for the features one-by-one as they land, so I've added this one on the enum change https://github.com/mozilla/standards-positions/issues/1453 On Wednesday, September 9, 2026 at 4:49:32 PM UTC+2 Mike Taylor wrote: > Is there any reason to not send a mozilla-standards position, at least so > they're aware we're shipping? > On 9/9/26 6:42 a.m., Yoav Weiss (@Shopify) wrote: > > LGTM3 > > On Tue, Sep 8, 2026 at 10:49 PM Rick Byers <[email protected]> wrote: > >> LGTM2 >> >> On Mon, Sep 7, 2026 at 5:22 PM Philip Jägenstedt <[email protected]> >> wrote: >> >>> LGTM1 >>> >>> On Fri, Sep 4, 2026 at 10:39 PM Chromestatus < >>> [email protected]> wrote: >>> >>>> *Contact emails* >>>> [email protected] >>>> >>>> *Specification* >>>> >>>> https://html.spec.whatwg.org/multipage/canvas.html#colour-spaces-and-colour-correction >>>> >>>> >>>> *Summary* >>>> Add srgb-linear and display-p3-linear color spaces (as defined by CSS) >>>> to PredefinedColorSpace for use with canvases. >>>> >>>> *Blink component* >>>> Blink>Canvas >>>> <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ECanvas%22> >>>> >>>> *Web Feature ID* >>>> canvas-2d-color-management >>>> <https://webstatus.dev/features/canvas-2d-color-management> >>>> >>>> *Motivation* >>>> Linear color spaces (where pixel values correspond linearly to >>>> luminance) are extremely commonly used in applications with connections to >>>> physical light rendering (e.g, games) or spatial processing (e.g, >>>> decimation, anti-aliasing, and interpolation). >>>> >>>> *Initial public proposal* >>>> *No information provided* >>>> >>>> *TAG review* >>>> https://github.com/w3ctag/design-reviews/issues/1194 (Note that this >>>> is for the full HDR on the web project, which this is a part of) >>>> >>>> *TAG review status* >>>> Issues addressed >>>> >>>> *Goals for experimentation* >>>> None >>>> >>>> *Risks* >>>> >>>> >>>> *Interoperability and Compatibility* >>>> *No information provided* >>>> >>>> *Gecko*: No signal >>>> >>>> *WebKit*: Positive Suggested by WebKit, already implemented in WebKit. >>>> >>>> *Web developers*: Positive Partners have repeatedly requested linear >>>> working color spaces >>>> >>>> *Other signals*: >>>> >>>> *Ergonomics* >>>> None >>>> >>>> *Activation* >>>> None >>>> >>>> *Security* >>>> None >>>> >>>> *WebView application risks* >>>> >>>> Does this intent deprecate or change behavior of existing APIs, such >>>> that it has potentially high risk for Android WebView-based applications? >>>> *No information provided* >>>> >>>> >>>> *Debuggability* >>>> The corresponding CSS color spaces are supported in DevTools (DevTools >>>> does not have any features related to canvas bitmap color spaces). >>>> >>>> *Will this feature be supported on all six Blink platforms (Windows, >>>> Mac, Linux, ChromeOS, Android, and Android WebView)?* >>>> Yes >>>> >>>> *Is this feature fully tested by web-platform-tests >>>> <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?* >>>> Yes >>>> API tests (setting and getting): >>>> https://wpt.fyi/results/html/canvas/element/manual/context-attributes/getContextAttributes.html >>>> >>>> Draw-and-readback tests: >>>> https://wpt.fyi/results/?label=experimental&label=master&aligned&q=2d.color.space >>>> >>>> Chromium CLs: >>>> https://chromium-review.git.corp.google.com/c/chromium/src/+/8313909 >>>> Roundtrip tests (toDataURL, toBlob, etc): >>>> https://chromium-review.git.corp.google.com/c/chromium/src/+/8312949 >>>> https://chromium-review.git.corp.google.com/c/chromium/src/+/8314209 >>>> >>>> *Flag name on about://flags* >>>> *No information provided* >>>> >>>> *Finch feature name* >>>> ColorSpacePredefinedLinearSpaces >>>> >>>> *Rollout plan* >>>> Will ship enabled for all users >>>> >>>> *Requires code in //chrome?* >>>> False >>>> >>>> *Tracking bug* >>>> https://issuetracker.google.com/issues/454152417 >>>> >>>> *Availability expectation* >>>> Feature is available on Web Platform Baseline within 12 months of >>>> launch in Chrome. >>>> >>>> *Adoption expectation* >>>> Feature is considered a best practice for some use case within 12 >>>> months of reaching Web Platform baseline.
