(I meant #ADADD8D8E6E6 and #ADD8E6 for LightBlue - got my numbers wrong; sorry.)

Is that right? Could you please check about this?
I was under the (perhaps mistaken) impression that Emacs treats colors
differently, depending on your display's color support. In particular, I thought
that `display-color-cells' would show how many colors are supported, and
therefore how many RGB hex digits would be appropriate (available) for a given
display. IOW, I thought that on some displays you might be able to use only
#RRGGBB, while on others you could use #RRRGGGBBB (where there would be a
perceived difference when using fewer or more digits).

If you're sure about what you say, then yes. But please check to be sure. Thx.
