Minecraft particle file?

I'm currently doing a Texture Pack mix and have seen that these paritels in the video are always red. Actually they should be green and if who is nearby they will be red… I wanted to look in the files of the texurepack where these red particles are but I couldn't find anything. Who can tell me where / how to change it

Thank you!

I would recommend you check the Particle tab.

But if you don't have that many files in one file, you can change each one and see which one solves the problem.

There's only footprint and particles
