gray(x%) as a shortcut for rgb(80,80,80)

[adius]

I think it would be cool if there was the possibility to use the rgb function with just one value as a shortcut.
What do you think?

gray(n%) would feel more natural to me.

+1 for this. I've had a gray() (well actually grey) function in my files for months, I use it all the time. Very very useful.

I'm definitely not willing to overload rgb() in a way that may end up being incompatible with the CSS spec. gray() may be doable, though.

gray() became part of the CSS4 draft 😄 .
gray() = gray( [<number> | <percentage>] [, <alpha-value>]? )

Hi,
I was hoping to get some guidance on this issue being a new contributor. I have come up with an implementation for gray() that is based on the way rgb() is done and it seems to work. I would like to know what would be the proper way to go about adding such a feature and what considerations should be taken.
Thanks
