First, it's meant for humans. As a gesture. Surely you've heard of those.
Second, it's not like CSS is not 50% ill-though BS legacy stuff all around, and some over-engineered crap in tons of sub-specs. A color name will hardly make any difference to anything.
There's a CSS color named 'Gainsboro', and a color named 'NavajoWhite' that's not super close to white. 'RebeccaPurple', from a pragmatic sense, is easier to understand than those two in my opinion.
While "gainsboro" as grey is now in the dictionary, used from rugs to Kate Spade pants, Wikipedia suggests it's from X11 colors with no real world usage before that.
Before you follow up with a rant on being downvoted for merely having a different opinion: I only speak for myself but I don't mind you saying you're opposed to this proposal. Sure, it makes me not like you but if I downvoted everyone I didn't like it'd be a full-time job.
The reason (at least, for me) is the rather insensitive way in which you expressed your opinion. Take a few steps back and reconsider what you wrote on what is essentially a thread about a father losing his daughter.
Your patience and civility are appreciated, but the GP was way beyond the pale. We've banned that account as a troll (at least until we get a promise that this won't happen again).
I'm not sure if the deadfly remark is some morbid joke, but I agree with the first half of your post.
While it is a great gesture to a man many of us look up to and are grateful for his work, where will it end, if we need to pay tribute in the form of specs to all the losses of people involved in developing the open web?
If share a cookie with a friend, you're that person who demands I share with everyone within earshot, aren't you?
Just take it for what it is. It's one act of kindness. Buying a sandwich for a homeless person doesn't mean every homeless person is now entitled to a sandwich from you.
