Answer 1

A generic solution would be something like:

var data = {
   black: ['abc'],
   red: ['xyz']
}

var result = _.mapObject(data, _.first)

which would give you:

{
    black: 'abc',
    red: 'xyz'
}

Answer 2

Just set that property to be the value of the array:

var original = {"black":["/file/d60f198e-dde5-4e5e-b2ab-1ee10c96a027.png"]}
original.black = original.black[0]
