I think it would be helpful to show a different wire color for things LabView believes could be complex numbers. Some functions like Root Find cannot be directly wired up to a Min & Max vi because the number could be complex.
Red is a horrible color for a wire. Red instinctly means "Error", "Danger", "Don't Do That".
There are only two ways to tell somebody thanks: Kudos and Marked Solutions Unofficial Forum Rules and Guidelines "Not that we are sufficient in ourselves to claim anything as coming from us, but our sufficiency is from God" - 2 Corinthians 3:5
We could make them blinking. Complex numbers... sometimes they're real... sometimes you just have to imagine them.
Kidding of course...
I don't use complex numbers often enough to have a real opinion on this idea, but I've heard some of the math guys say that they never found it a problem that the real and the complex numbers both used orange because mostly they used only one or the other in any given VI. Don't know how true that is for users generally.
Certainly if this idea got enough kudos it would be possible to change it.
As I have said on other ideas about colors, color blind people do not want more colors!
If a distinctive wire is needed, and I am not convinced it is, do something 2-dimensional. The image below was created by placing a boolean wire (source and sink hidden behind numerics) adjacent to the numeric wire. The dots would need to be the same color as the numeric wire. (Someone told me booleans and numerics are different colors - I can't tell on 1-pixel wide objects like wires.)
