That's the expected behavior. See here.

Color array items that are non-numeric and invalid colors string (e.g. undefined in your example) are drawn as #444.

Is the current that surprising?

Ah, I see, it is a bit surprising to me. Something about that syntax made me think you could restyle particular marks without side-effects...

On a related note, I also find this behavior surprising http://codepen.io/cpsievert/pen/dOyryr

... and I'm surprised that you forgot about this restyle q-u-i-r-k

Plotly.restyle(gd, {'marker.color': [["red", "blue"]]});

is what you want I believe.

Thanks. The biggest reason for opening this ticket was because I wasn’t sure how to get restyle() to do what I wanted, but this comment fixes that
