浅色Cocos2dx上的GL混合

Question

I am using CCBlade in my game from here which creates a blade effect on swipe, it works great on black screen. But I got a problem when I tried to use it in lighter color screen, my game has light blue sky color . I think there is something to do with the blending which CCBlade using. It is currently using

GL::blendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA);

What could be the correct combination? So that the blade effect is visible on light color. See the image below for more clarification

Thanks.
