fillcolor boolean discrepancy

Participant ,

Hey everyone,

Could someone explain the below (console) behavior for me? ( Nb. f1. is a text field that is gray.)

f1.fillColor==color.gray

false

f1.fillColor

G,0.5

color.gray

G,0.5

I'd like to use the background color for booleans , but because the top comparison fails I'm at a loss.

For this particular instance I have a workaround but for my overall understanding I'd be happy to know why this works this way

Color objects are actually an array, and arrays can't be compared to each other directly in JS.

So this code will return false:

[1]  == [1]

The solution is to use the built-in equal method of the color object.

For example, this will return true:

color.equal(color.red, ["RGB", 1, 0, 0])

You can use this:

f1.fillColor.join('|') == color.gray.join('|')

Why would you want to do that if you have a perfectly good built-in comparison method, that even converts the two values to the same color-space, if needed?
For example, this returns true:

color.equal(["RGB",1,1,0], ["CMYK",0,0,1,0])

This returns false:

["RGB",1,1,0].join('|') == ["CMYK",0,0,1,0].join('|')
