I love using column colours on a ratings column

It could break every template that uses it.

     elif r >=#4 then '#94E4C9'
     elif r >=#3 then '#FE657D'    
     elif r >=#2 then '#FCB2A9'
     elif r >=#1 then '#FEDC78'
 

     fi

Go to Settings> Look and Feel> Column Colouring> Add Advanced Rule (it's a button at the bottom left of the dialogue box)


Change "Set the colour of the column" to the ratings column and paste the code into the template box and you should be good to go.

Ans so much thanks to ownedbycats your idea is genius! I love ideas to make calibre prettier.

Now yes, thanks for sharing!

        2.1, '#94E4C9',
        3.1, '#FE657D',
        4.1, '#94E4C9',
             '#2EAB64')

I used 1.1 instead of 1 etc. because the comparisons are 'less than'. I should have made it <= when I added first_matching_cmp() to the template language. Oh well, too late now.

Thanks Chaley, this is fantastic 💚
