When Forced Colors Mode is enabled, the ‘color’ property is inherited, and we’ve set ‘forced-color-adjust: preserve-parent-color', the ‘color’ property will compute to the used value of its parent. Otherwise, ‘forced-color-adjust: preserve-parent-color' value behaves the same as ‘forced-color-adjust: none’. Motivation ‘forced-color-adjust' is a CSS property that allows developers to opt out of Forced Colors Mode. Previously, there were two supported values: ‘auto’ and ‘none’, which can be used to control whether or not an element’s styles are adjusted by the UA in Forced Colors Mode. A third value, ‘preserve-parent-color', has recently been introduced in the spec, which provides similar behavior to ‘none’, except that it also allows an element to inherit its parent's used ‘color’ value. In other words, ‘preserve-parent-color' provides the ability for an element to inherit its parent’s Forced Colors Mode adjusted ‘color’ value. The intention of ‘preserve-parent-color’ is to get a reasonable behavior for SVG icons that utilize ‘currentColor’ when styling ‘fill’ and ‘stroke’ in Forced Colors Mode, as described in [css-color-adjust-1] Spec currently breaks use of currentColor for SVG icons in WHCM · Issue #6310 · w3c/csswg-drafts · GitHub<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fw3c%2Fcsswg-drafts%2Fissues%2F6310&data=04%7C01%7CSara.Tang%40microsoft.com%7C62d286347825457df11408d99fc9f115%7C72f988bf86f141af91ab2d7cd011db47%7C0%7C0%7C637716512028553911%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=uad57jXrwttyZCLj2jQfmNV%2BI%2FnGayCnrJejGOvygFQ%3D&reserved=0>. The use of ‘currentColor’ when styling an SVG icon is a common pattern used by authors to ensure an accessible experience in Forced Colors Mode. For example, in this sample logo,<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcodepen.io%2Fsomelaniesaid%2Fpen%2FYzqxogg&data=04%7C01%7CSara.Tang%40microsoft.com%7C62d286347825457df11408d99fc9f115%7C72f988bf86f141af91ab2d7cd011db47%7C0%7C0%7C637716512028563880%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=C2jM5UsaKengIfmQoohieuTLJzai2MzdO9xaCeyai3g%3D&reserved=0> an author would expect the logo to automatically adjust to use the ‘CanvasText’ system color for ‘fill’ and ‘stroke’ in Forced Colors Mode, as a result of setting each to ‘currentColor’. This behavior, however, became broken when we moved from forcing colors at computed value time to used value time: [css-color-adjust-1] Is forced color computed or used value? · Issue #4915 · w3c/csswg-drafts · GitHub<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fw3c%2Fcsswg-drafts%2Fissues%2F4915&data=04%7C01%7CSara.Tang%40microsoft.com%7C62d286347825457df11408d99fc9f115%7C72f988bf86f141af91ab2d7cd011db47%7C0%7C0%7C637716512028563880%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=r%2FrOfDV1w7MorTDvytFt2lJKVYi8GK91Ecu47KpQC%2Bk%3D&reserved=0>.

The new ‘preserve-parent-color' value was added to address this common SVG use case. By changing the default value of ‘forced-color-adjust’ for SVGs from ‘none’ to ‘preserve-parent-color', SVG icons that make use of ‘currentColor’ will now inherit the used ‘color’ value of its parent, as expected. It is important to note that this may break SVGs that expect the opposite inheritance behavior for the ‘color’ property. However, the behavior of `preserve-parent-color` handles the most common SVG use cases, and the behavior better matches legacy implementations of High Contrast Mode.
