Green One Color Gradient as Expression

[Nocto]

Hey guys,

I need this Setup as Background Expression, but I cant get it Right.

I used something like  if(Typ..open_close = 'open', ColorMix1(.75,red(),green())

But no changes from green into a darker green were applied with this Expression.

Hopefully you can help me out.

is it possible that the field [Typ..open_close] is not equal to 'open'?  if so then the result is null.  suggest you just try the colormix1 without the if (obviously, it will be static) but just so you can check if the function works for you or not then work your way back to the if statement.  second suggestion, add an else option to your if statement.
