How to get the options of a configurable attribute in Magento?

Question

we want to export/import configurable products through the Magento-API in another system. What is important for us, are the values of the configurable products like a T-Shirt which has 3 colors (red, green and blue).

We receive the configurable attributes with the following function:

public function options($productId, $store = null, $identifierType = null)
{
    $product = $this->_getProduct($productId, $store, $identifierType);

    if (!$product->getId()) {
        $this->_fault('not_exists');
    }

    $configurableAttributeCollection = $product->getTypeInstance()->getConfigurableAttributes();

    $result = array();
    foreach($configurableAttributeCollection as $attribute){
        $result[$attribute->getProductAttribute()->getAttributeCode()] = $attribute->getProductAttribute()->getFrontend()->getLabel();
        //Attr-Code:    $attribute->getProductAttribute()->getAttributeCode()
        //Attr-Label:   $attribute->getProductAttribute()->getFrontend()->getLabel()
        //Attr-Id:      $attribute->getProductAttribute()->getId()
    }


    return $result;
}

But how is it possible to get the options used in that product (e.a. blue, green, red if the configurable attribute is "color") with the now available label/id from the configurable attribute which we got through the above function?

Answers are very appreciated!

The question is not clear. What do you mean by "get the used values in that product with the now available label/id? — Andrey Tserkus
We want to get the options like red, blue and green (if the configurable attribute is "color"). And with the above stated funtion we get the information about the used configurable attributes. — Tim
So you want the "color options" for a given product [red, green, blue]? — Jared Farrish

Since we couldn't find a better solution, this is what I came up with:

public function options($productId, $store = null, $identifierType = null)
{
    $_product = $this->_getProduct($productId, $store, $identifierType);

    if (!$_product->getId()) {
        $this->_fault('not_exists');
    }

    //Load all simple products
    $products = array();
    $allProducts = $_product->getTypeInstance(true)->getUsedProducts(null, $_product);
    foreach ($allProducts as $product) {
        if ($product->isSaleable()) {
            $products[] = $product;
        } else {
            $products[] = $product;
        }
    }

    //Load all used configurable attributes
    $configurableAttributeCollection = $_product->getTypeInstance()->getConfigurableAttributes();

    $result = array();
    //Get combinations
    foreach ($products as $product) {
        $items = array();
        foreach($configurableAttributeCollection as $attribute) {
            $attrValue = $product->getResource()->getAttribute($attribute->getProductAttribute()->getAttributeCode())->getFrontend();
            $attrCode = $attribute->getProductAttribute()->getAttributeCode();
            $value = $attrValue->getValue($product);
            $items[$attrCode] = $value[0];
        }
        $result[] = $items;
    }

    return $result;
}

Hope this helps anybody.
