How to remove enum from string?

I have a set of enum values and an input string, and in case the string has a suffix which is one of the enum names, I want to delete it.

For example, let's say I have 

enum colors { red, blue, green, white }

And I receive the input string "str = evergreen", I want to do something like 

if (str.endsWith(colors)) {
   output = str.trimSuffix(colors)
}

and get the string ever in output. Modifying str itself instead of saving it to a new variable is also fine.

is there a simple and/or elegant way to do it without hard coding the enum as array of strings and iterate over it?

This code will remove any suffix from str that is defined in the enum below

var values = Enum.GetNames(typeof(colors));
var str = "evergreen";

var suffix = values.OrderByDescending(v => v.Length)
    .FirstOrDefault(v => str.EndsWith(v));

if(suffix != null)
{
    str = str.Substring(0, str.Length - suffix.Length);
}

enum colors { 
   red,
   blue,
   green,
   white 
}
