Split string on hex colour

Similar to my previous question I have a string with hex colours, no spaces and named colours.

#f503e1Pink59bf22greeny-green#"f7b925"orange#fffwhite

How can I split the string on each hex colour - split the string AND keep the delimiter?

#f503e1Pink
59bf22greeny-green
#"f7b925"orange
#fffwhite

The hex colours may be preceded by a # and may be surrounded by quotes and is either three or six characters long. The named colours can be any combination of characters of undetermined length.

(#?\"?[a-fA-F0-9]{3,6}\"?)

If i undersood well you nee dthe following: i supposed a color (not hexa color) contain only letters . greeny-green is not a single color, is greeny and green. if this rule is eronate, please replace the [a-z]+ from the end with [a-z-]+ or include any other character needed.

var string = '#f503e1Pink59bf22greeny-green#"f7b925"orange#fffwhite',
matches= string .match(/(#?\"?[a-f0-9]{6}\"?|#?\"?[a-f0-9]{3}\"?|[a-z]+)/gi);

console.log(matches);

This is what I have (and it's not pretty)

str = "#f503e1Pink59bf22greeny-green#\"f7b925\"orange#fffwhite";

reg = /(#?\"?[a-fA-F0-9]{3,6}\"?)/gim

var res = str.match(reg);

str2 = str
var results = "";
h = [];
for (var i = 0; i < res.length; i++)
{
    var hex = res[i];
    results += hex + "\n";
    h.push(hex);
    str2 = str2.replace(hex, ", ");
}

sp = str2.split(", ");

// loose the first element ","
sp.shift();
alert(sp);


for (var i = 0; i < h.length; i++)
{
    results += h[i] + " " + sp[i] + "\n";
}

alert(results);

As other colleagues mentioned: there's no 100% working solution for your current input that will cover all possible cases.
To cover your particular input and output consider the following approach using String.match() function:

var str = '#f503e1Pink59bf22greeny-green#"f7b925"orange#fffwhite',
    colors = str.match(/#?\"?[a-f0-9]{3,6}\"?[a-z-]+/gi);

console.log(colors);
