ICC 4.2 defines rendering intents including blackpoint compensation. This is primarily useful for CMYK where, epecially on poorer quality papers, the deepest black is much lighter than Lab 0 0 0. For RGB colorspaces, it is typical to convery assuming RGB 0 0 0 is Lab 0 0 0 and then do any flare compensation as a separate step. For video, especially narrowband video with headroom and footroom, a PLUGE signal is used to set a true black. -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/299#issuecomment-688968293 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-configReceived on Tuesday, 8 September 2020 15:48:57 UTC
