Luminance is outputting grayscale

Hi Finn,

Maybe I'm misunderstanding the intention of this code.
I was thinking, if you start with for example #0000ff ( luminance 30 ) and then you give #ff0000 ( luminance 54 ), you would be getting either the first color or the second color but with the luminance of the other color ... like red would return #af0000 or something with the luminance of 30.

Anyway ... I don't get anything remotely close to that. I just get a grayscale color with a luminance value that doesn't match up with anything.

Here's an example.

var myNewColor = [0, 163, 239] // Luminance of 63

// Start with [0,0,141] = Luminance of 13
console.log("myNewColor converted: " + fixedLuminance([0, 0, 141], myNewColor));
// returns 41,41,41 = Luminance of 17

console.log("myNewColor: " + myNewColor);

Thanks
