What do people think about #ffffbb, then? It's the other color Juri 
mentioned.

Stefan? Eli?

It's also relatively low-key like "lemon chiffon", but a bit more 
noticeable. And it seems to fit the default theme very well.

I guess we'll fall back to "khaki1" if the more radical options are not 
accepted.

If we're talking about dark background, it should be at least khaki4 
(the text is hard to read otherwise), or the RoyalBlue4 I suggested as 
the tweak for the current dark-bg color of this face.

Although the current RoyalBlue3 seems to have about the same level of 
brightness as khaki4. So it's not out of the question to just leave the 
current color there.

If we change the dark-bg color to khaki, I think we'd also need to 
change the spec for ((class color) (min-colors 8) (background dark)), 
and setting it to "yellow" is probably not a good idea.

Wish we had some dark-background users in this discussion.
