Re: [csswg-drafts] [css-color-4] Predefined colorspaces (#4056)

The CSS Working Group just discussed `Predefined colorspaces  (renaming image-p3 to display-p3)`, and agreed to the following:

* `RESOLVED: Take what we're calling image-p3 in our spec and rename it to display-p3`

<details><summary>The full IRC log of that discussion</summary>
&lt;dael> Topic: Predefined colorspaces  (renaming image-p3 to display-p3)<br>

&lt;chris> I looked into the edit history, there were a number of changes drom dci-p3 to where we are now. Rik was the main contributor; there was discussion on the commits. See for example https://github.com/w3c/csswg-drafts/pull/557/commits/644c4c49b86d97bb59bf74e533bdfbe339f3d176<br>

&lt;dael> chris: Looked at htis. When originally put in spec confusion between dcip3 and what apple used. I originally called it dcip3 and that was wrong for many reasons<br>
&lt;dael> chris: Thought had resolution, but can't find. Went through edit history and it went through name changes. I'm happy changing to to what everyone knows it as<br>
&lt;dael> dino: My memory is not great. At some point I posted the profile for it given the idea it can be linked form the spec. I'm in favor of display-p3. Also willing to add another named to dci-p3 but I don't think there's a need<br>
&lt;dael> chris: I don't think there is. dci-p3 has strange greenish white and designed for use in digital cinema. Not appropriate for web<br>
&lt;dael> dino: That's the main driver for Apple creating what we call display-p3<br>
&lt;dael> tantek: You said because it's designed for dark env it's not appropriate for web<br>
&lt;dael> dino: Pitch black rooms<br>
&lt;dael> tantek: People do use the web in black rooms<br>
&lt;dael> dino: This is just hte convenience method. You can get the same result using display-p3. It just happens to have been calibrated for different env.<br>
&lt;dael> tantek: Is that calibration not useful when looking at web in the dark?<br>
&lt;dael> dino: If you're writing to be used in something like a cinema sure<br>
&lt;dael> astearns: THt's an argument to add dci-p3, but this is about what do we call the thing that we know is not dci-p3 and we want to support it<br>
&lt;dael> AmeliaBR: Adding sep profile can defer until demand. There is demand to match the thing Apple does. If the definition is match Apple then we should match the name unless there's trademark reasons<br>
&lt;tantek> s/black rooms/dark rooms<br>
&lt;tantek> s/just hte/just the<br>
&lt;dael> dino: Nothing apple specific about this other than we gave it a name. That's why I posted the file. There's nothing secret or protected about this<br>
&lt;dael> chris: Given that I would like to call for resolution<br>
&lt;dael> astearns: I could not find reason why we changed from display-p3 to image-p3. There's some discussion about how web isn't only for displayed, but not terribly compelling.<br>
&lt;dael> astearns: Prop: Take what we're calling image-p3 in our spec and rename it to display-p3<br>
&lt;dael> astearns: Objections?<br>
&lt;dael> RESOLVED: Take what we're calling image-p3 in our spec and rename it to display-p3<br>
&lt;dael> dino: Anything we can do in CSS to stop people from using their phone in a cinema?<br>
&lt;dael> astearns: Happy to follow the incubation process<br>
