I wrote earlier today in response to a 16-bit color

This "bug" turns out to be operator error. I forgot
to restart IDL after setting my display to 16-bit
color mode. So, yes, 16-bit color is similar to
24-bit color.

You can also draw a plot in yellow using hexadecimal
notation for the color, like this:

Plot, data, Color='00FFFF'x

Cheers,

David
