Multistate image with multiple points input

[sbaik]

I need a light that outputs 4 different colors. I have 4 binary inputs that will be in different combinations. How would I go about doing so? I tried searching with no luck.
Basically, A. valve opening, B. closing, C. not fully open, D. not fully closed.

I need output when following combination is true.
C.
D.
ACD.
BC.
BCD.
AD.

Thanks in advance.

A multi-state meta data point would probably be your easiest option.

Add the 4 binary data points as context points. The script would look something like this -

var a = contextA.value << 0;
var b = contextB.value << 1;
var c = contextC.value << 2;
var d = contextD.value << 3;

return a | b | c | d;
