SVG条纹有2种颜色

Question

在这个例子中： https://jsfiddle.net/ywb77uhv/

为什么在将条带路径颜色更改为白色而不是白色时会破坏渲染？如何改变路径颜色？

//config.yml
# app/config/config.yml
nelmio_api_doc: ~

// app/config/routing.yml
NelmioApiDocBundle:
    resource: "@NelmioApiDocBundle/Resources/config/routing.yml"
    prefix:   /api/doc

// routing.yml
    profile_rest_oauth:
        resource: "@ProfileBundle/Rest/Oauth/RestController.php"
        type:     rest
        prefix:   /api/oauth

    profile_rest:
        resource: "@ProfileBundle/Rest/Xwsse/RestController.php"
        type:     rest
        prefix:   /api


//RestController
use FOS\RestBundle\Controller\FOSRestController;
use FOS\RestBundle\Controller\Annotations;
use Nelmio\ApiDocBundle\Annotation\ApiDoc;
use Symfony\Component\HttpFoundation\Request;

class RestController extends FOSRestController
{
    /**
     * @ApiDoc(
     *   description="Update profile for user",
     *   section="profile",
     *   https=true,
     *   statusCodes={
     *       200="OK, user profile updated",
     *       400="Wrong input, no update"
     *   },
     *   views = { "oauth" }
     * )
     */
    public function putProfileAction(Request $request)
    {
    }
//composer.json
   "nelmio/api-doc-bundle": "2.7.0",

因为在SVG中，蒙版使用蒙版定义中颜色的亮度来计算蒙版的阿尔法值。白色= 100％不透明度。红色= 70％不透明度，蓝色=青少年不透明度。
