how to install the vim plugin I already put the files in the correct folder but nothing happen?

I download vim-coloresque-master and put the file in the correct folder,
vim80/ and vimfiles/ folder, both put the files in the correct folder, I
want to highlight the color number in the css file,
but nothing happens,

like the code like this:
background-color: #eae4df;

the #eae4df will be highlight by the color.

Why this happen and how to fix it?
