Okay. I’m hopelessly infected by this, so I have to reply.
I didn’t know that we’ve been voting, but that’s fine. However, I’m curious about your opinion. I don’t understand why you are asking for technical concerns. Was this a technical problem to begin with?
And if you must, adding a new color name slows down the browser; there’s no way that something can be just put in for free. It might be infinitesimal on individual cases, but significant considering the entire population of browsers affected. Now where does this extra computation power go? Do they do anything helpful? Where is the technical benefit? If the benefit is non-technical, can we then talk about non-technical concerns?
In fact, I see many other “technical concerns” listed above, too (“CSS color list should not be an obituary"); maybe they aren’t the kind you are referring to. I have been wondering what kind of technical concern actually counts and would change your mind. Would you reconsider it if the new color name delays every page load by an extra 1s? Or how much does it have to be? Are we doing this just because it is a small enough price that we’ll have to pay and do not care? (Actually, would you mind adding a few other names while we are at it? I suppose there is a lack of specific technical concerns.)
I do not actually think the above is a good enough reason to not add the color name because technicality is quite irrelevant on this subject, but since you mentioned very specifically about technical concerns, here you go. I hope to be enlightened in case I missed something.
