How to restore name of rbga?

[Denis535]

Stylus implicitly converts color keywords to rgba, but sometimes this is very undesirable and I would like to be able to get the original name of rgba.
How can I do this?

Stylus(FS.readFileSync(src, 'utf8'))
.define('name', function(obj) {
    return obj.name;
})
.define('nameof', function(obj) {
    return obj.name;
});

value = nameof(value) if typeof(value) == 'function' or typeof(value) == 'rgba'
