No offence: just asking:
Sometimes your reddish dots are below price, sometimes they are above price.
Sometimes your blue dots are below price, sometimes they are above price.
Give me a hint, here: how does this help in actual trading?
Blue = sell or buy
Reddish = sell or buy
Or does it "simply" mean: price has reached an extreme and may go the other way?
(On my screen the slow zigzag never produces a dot on its own; we either have a fast zigzag-dot or both zigzag-dots: why is that?
If they don't indicate direction - which red and blue mostly do in indicators - (but price extremes) wouldn't it be better (i. e. less confusing) to use similar colour but different size?)
Maybe, "classical" colouring may even be better; see repainting zigzag screenshot:
