Also, `#fff` is ambigous -- if you mean device colour, then there's no brightness (nits) specified at all, it may be 200 or 2000 or 10,000. If sRGB is implied, as in `#fff in sRGB colour space` then the standard specifies 80 nits, so when you say you don't want brighter than that, then you can't have much of HDR since sRGB precludes HDR by definition (can't go brighter than 80 nits for the "whitepoint" aka white).
I think if you want HDR you need a different colour space entirely, which either has a different peak brightness, or one where the brightness is specified additionally to e.g. R, G and B primaries. But here my HDR knowledge is weak -- perhaps someone else may chime in. I just find colour science fascinating, sorry to go on a tangent here.
And no, #fff is not a "device color". The syntax originates from the web where sRGB is implied ever since we had displays brighter than that.
`#fff` is device color, it's short for `#ffffff` which is 24-bit RGB that predates sRGB, as does true color device support. I was sending 24-bit RGB to VESA-compliant graphics cards before sRGB became a thing. `#fff` was supported by Photoshop and Macromedia products as straightforward device colour format, before sRGB was adopted by at least the latter, mind you. The use by CSS is co-incidental, not where the format was introduced.
Hmm, I suspect that almost everyone who works in the terminal has never done this. I don’t really care what the colors look like, beyond choosing between whatever built in themes my terminal has. Is this really the minority experience?
The article is well argued and well written, as far as I’m concerned.
What’s needed if you really want adoption is to define a term; something like 256-ex for extended. Or whatever. But folks and apps need to be able to say; we’ve implemented or we support 256-ex. Without this label is hard to drive adoption.
The heartbleed thing from a few years back best taught me this.
Good luck I hope to see broad adoption it’s a great idea.
Give it a name, better yet move the copy onto a website with the same name also and a little icon folks can add to their website if they implement this k to their terminal app.
Damn if only there was some other system that could be operating with that in mind
(And if you don't make such an extension, what, you have no third-party graphics drivers for example?)
