Attribute options update

Hello,

I am having difficulties for adding new color in my color attribute, when i click on add new button it will show me all the colors that exist but i want to add new color that doesn’t exist (for new products variations) but i don’t see where to do it.
I want to add “Gold ” an “Silver” into my color attribute but i don’t see how to do it with your plugin.
Please help

i bought the plugin on codecanyon

Thank you
