      Dear Hans van der Meer,

Thank you for your sample code.
I learned how to pass the value of the variables.
BTW, if I change “orange” to “red” or “green”, it is working fine. I think that  “orange” is not the predefined color. There is no color “orange” in the  MetaFun manual either.

Thank you.

Best regards, 
Dalyoung
