From faa7627ea41b1ce372bae7f0d2ae36e9b15a97a3 Mon Sep 17 00:00:00 2001 From: Héctor Ramón Jiménez Date: Wed, 31 May 2023 21:31:58 +0200 Subject: Introduce `web-colors` feature flag to enable sRGB linear blending This is how browsers perform color management. They treat gamma-corrected sRGB colors as if they were linear RGB. Correctness aside, this mode is introduced for legacy reasons. Most UI/UX tooling uses this color management as well, and many have created an intuition about how color should behave from interacting with a browser. This feature flag should facilitate application development with `iced` in those cases.
