Can brush tool or mixer brush tool duplicate exact images?

I want to be able to create a brush using an image, so that the exact image is replicated. Not just the shape of the image. I have a png illustration of a leaf that I want to be able to replicate by the hundreds as part of the creation of a tree. The leaf has a green blade, yellowish tint here and there, some red spots. So, how can I make a brush that would allow me to paint on that exact leaf, green blade, yellowish tint, red spots and all, by the hundreds? I hope I'm making sense.  I saw a 3-year-old tutorial that showed how to do this using the mixer brush tool. But I can't seem to recreate his technique using PS CC 2023. I am able to create a brush that uses the shape of this particular leaf. But, alas, then I'm only able to paint solid color leaves with blending mode and transparency options. Not what I want.
