hex_pattern question

[slipsnip]

This is a question regarding the variable colorizer_hex_pattern and getting it to match rgb:a0/a0/a0 for example, found in a config file. I tried setting let g:colorizer_hex_pattern = ['rgb:', '\%(\x\{2}\/\?\)\{3}', '\>'] and toggling colorizer with :ColorToggle. I know that the colorizer is working because other colours in the file such as red are correctly rendered with a red background, but my hex_pattern seems ignored. If I try entering the pattern into a / search, it finds and highlights what I want to be colourized.

If you could lend any help with getting this to work that would be appreciated. Thank you.

To add further context of the use case, the configuration file I am editing states that colors must conform to the XQueryColor specification man 3 XQueryColor and search for color names.

Hm, need to check that.

It should work with a pattern like this:

     let g:colorizer_hex_pattern = ['rgb:', '\%(\x\x\/\x\x\/\x\x\)', '']

I don't have a manpage for XQueryColor, but I assume this should work.
