I imagine that two decisions need to be made by 2d content running in a VR or mixed reality display: - Is the browser content the primary focus of the user, possibly occupying a large portion of the user's field of view? .. Or is it a secondary activity to the user's interaction in the virtual or real world (eg. displayed on a virtual tablet within a VR environment or placed in a smaller region of the user's vision off to the side). - Is the display capable of rendering dark colors over a bright background? Some displays are optically transparent and can only add additional light to the environment. In this case, black is invisible / fully transparent and bright colors always have the most contrast. Perhaps two separate keywords could make this more expressive: **environment-blending:** _opaque_ - The 2d content is fully opaque and able to render dark colors in a bright environment. Examples: Traditional 2d monitors, tablets, phones, VR headsets that are not optically transparent, AR devices that use a pass-through camera feed. _additive_ - The web content is blended with the real world with additive mixing. Black is fully transparent and bright colors have the most contrast. Examples: Windshield head's-up-display, optically transparent displays such as the Microsoft Hololens and Meta2. _subtractive_ - The web content is blended with the real world using subtractive mixing. White is fully transparent and dark colors have the most contrast. Examples: An LCD display embedded in a bathroom mirror. **reality** _2D_ - Viewed on a traditional 2d display / monitor / tablet / phone.. _mixed_ - Viewed in a AR/MR environment where the real world is visible behind the web content, either through an optically transparent display or a composited camera feed. In a "mixed" reality, even when focused, the content may not want to distract the user from their surroundings and is often a secondary activity. _virtual_ - Viewed in a VR environment where the user's view to the real world is obscured. When focused, the content is expected to be the primary activity. -- GitHub Notification of comment by kearwood Please view or discuss this issue at https://github.com/w3c/csswg-drafts/pull/2719#issuecomment-393980615 using your GitHub account
