How would I change the color of some of these notes?

[MadLad0913]

These notes are frustratingly similar in color, and I would like to change some of them to the color white. Does anyone have some advice on how to do this? Change to color, roto-scoping, etc. do not work because the colors are so similar. Any, tips, advice, tutorials, etc. are much appreciated. Reference image below.

I'm guessing that those notes are moving as sound is paying. So if tyhat is the case I would try to track mask (Using the After Effects Mask Tracker) and effect to mask  or use built in Mocha planar tracker  (New: Mocha AE CC in Adobe After Effects 2019 - YouTube ).

Thank you, I will try this when I get home later from work.

Could you provide some more exact details about what you are trying to build.

For example, are all the shapes in a single column to be the same colour? If so, this would be a whole lot easier as it wouldn't require tracking. You could, for example, apply a Lumetri Color effect which would alter such things as contrast and saturation to push the light blue to white while keeping the black, black. You could then mask this effect and throw on a little feather for good measure.

Sorry for the late reply. I can see what you’re saying, using gradients to color the vertical lines could work, but it would take quite a long time. They would all still be similar anyways, just in a different color. Thank you for the advice though!

What I’m trying to build are similar videos to those of AtinPiano. However, I want some shapes colored white for more color variety. This, howeve, I do not know how to do because all the other options I tried haven’t worked. All the tools that change color changes ALL the notes instead of just one because they are such a similar color.

If this is pre-baked footage, then using masking and layer duplicates with separate colorization effects would be pretty much your only option. If the chord bars and notes scroll vertically and stay in the same columns, a quick way might also be to use layers with gradients on top using blending modes to dim some regions and re-colorize others as the elements pass beneath them.
