I'm pretty certain I'm missing your meaning. If I create a solid to transparent gradient in PhotoShop, I fill the shape (let's say a rectangle) with a solid color (let's say, green) in the rgb channel, and then put a black to white gradient into the alpha channel. I don't create a green to black gradient in the rgb channel the way safari does.
