Re: [csswg-drafts] [css-color] Working Color Space

The Working Group just discussed `Color`, and agreed to the following resolutions:

* `RESOLVED: Chris to do more work :)`

<details><summary>The full IRC log of that discussion</summary>
&lt;eae> Topic: Color<br>
&lt;Chris_> github: https://github.com/w3c/csswg-drafts/issues/300<br>
&lt;eae> Chris_: This issue is about making computations on color boundaries.<br>
&lt;eae> Chris_: If used in a gradient, transitions, animations, etc.<br>
&lt;eae> Chris_: Right now, by default, given that we've never had anything outside of srgb, is that it happens in srgb which is unfortunate. You'll end up with the wrong color due to the gamma curve.<br>
&lt;eae> Chris_: We've had several resolutions where we don't have the right color space.<br>
&lt;eae> Chris_: In April we discussed this and someone suggested a linear 16 bit color space.<br>
&lt;eae> Chris_: That would allow colors outisde of the srgb gamma to be expressed. Another option would be to have it be unbounded.<br>
&lt;leaverou> s/outisde of the srgb gamma/outisde of the srgb gamut/<br>
&lt;eae> Chris_: I'd like to push this forward to have spec text about this.<br>
&lt;eae> Chris_: There will be people here at 3:30 that are exerts in this and will have an in-depth dicussion about it.<br>
&lt;eae> Chris_: One of the reasons I started this community group is to get expert input - should help the spec move forward.<br>
&lt;eae> I don't have a better proposal yet. Does anyone have any thoughts on this?<br>
&lt;dbaron> q+<br>
&lt;eae> pkerr: You need to do you calculations in a linear space. Whether it is sRGB or float-16 that gives you the same flexibility but with better math<br>
&lt;eae> pkerr: Gives an infine space between 0 and 1<br>
&lt;eae> Chris_: The movie industry likes having absolute values defined.<br>
&lt;eae> pkerr: Linear pixels is the way to go.<br>
&lt;astearns> ack bkardell_<br>
&lt;astearns> ack dbaron<br>
&lt;smfr> q+<br>
&lt;eae> dbaron: One comment: I'm fine with putting stuff in spec that isn't quite sure yet but please stick a note on it to explain that/<br>
&lt;dbaron> ack next<br>
&lt;eae> smfr: You can't change the color space to be linear without breaking stuff. A lot of pages have assumptions that would break. Authors needs to opt in.<br>
&lt;Rossen> q?<br>
&lt;eae> pkerr: When I said use linear I meant use it for the math and then convert back, not necessarily switching everything to linear.<br>
&lt;eae> RESOLVED: Chris to do more work :)<br>
