Lua - Using string.find to return true if between 2 special characters

I need a pattern that will work with string.find (or string.match if necessary) that will return true if a "table path" string matches. This is my function:

local function FindValueFromPattern(myTable, pattern, previousPath)
    for key, value in pairs(myTable) do
        local path;

        if (not previousPath) then
            path = key;
        else
            path = string.format("%s.%s", previousPath, key);
        end

        if (path:find(pattern)) then
            return value;
        elseif (type(value) == "table") then
            value = FindValueFromPattern(value, pattern, path);

            if (value ~= nil) then
               return value;
            end
        end
    end

    return nil;
end

local tbl = {}
tbl.settings = {};
tbl.settings.module = {};
tbl.settings.module.appearance = {};
tbl.settings.module.appearance.color = "blue";

print(FindValueFromPattern(tbl, "settings.module.appearance.color")); -- prints "blue";

The code above works BUT I want to now change the pattern to:

"module.<ANY>.color" where <ANY> is any child table of "module" and also has a child table called "color", so when traversing down the table, a value will be returned regardless of what table is used (does not have to be the appearance table):

-- should also print "blue" ("setting." should not be required);
print(FindValueFromPattern(tbl, "module.<ANY>.color"));

Rather than returning found values straight away, I may have to change the logic to insert found values in a table and then return the table after the for-loop but I wrote this quickly to illustrate the problem.

So the question is, what would that pattern look like? Thank you.
