life component particals color change

hi everyone.I do making a hand interactive design and I want the particles to change color depending on the position of the hand movement, but I couldn’t find a useful resource. Does anyone have any information?

Hi @nzlbtldmryl,

welcome to the community.
the approach to take will greatly depend on how your particle system and interaction is setup so far. Can you share your progress and explain your approach?

cheers
