Hi, I want to create a particular scroll effect, it’s similar at this Edelschwarz Alpine Bio Spirits

In my case I would like the fixed image of the bottle to change colour during scrolling, and also the background behind it to change colour during scrolling, to make it clearer I would like in the first block there to be a green background and a yellow bottle, then as I scroll a red background with a pink bottle comes up, but in all this the bottle must always remain still in the same position. I don’t know if I’ve managed to explain myself…

Thank’s!!
