I want to let particle color but no this panel. Another is about particle that penetrate plane.I find blender no deflector panel that can keep particle away from penetrating.

Thanks.

Can any experts help out here?

I am far from an expert on particles considering it is an area of Blender I've only just begun playing with in the last couple weeks but if you are just trying to keep particles from going through something, then under physics you can just set that object to be a collision object. Here's a screenshot where I have two planes in the scene, one is emitting particles (just using some basic UV spheres I have on another layer as the particles so that it is easier to see) and the other is set as a collision object. See how the particles are not passing through the bottom plane? Is that the effect you are going for?

Yes,I get it.But if no collision,how to let water has no penetrating through cup?AS I know 3dmax that has deflector function.But I cannot find it in blender. And how to material particle,give it color? Thanks.

For the collisions part: Are you actually using particles for the simulation or are you using a fluid sim?

If you are using particles then you need to set the cup as a collision object.

If you are using a fluid physics then the cup needs to be set as an obstacle in the physics/fluid settings. Maybe this video can help: https://www.youtube.com/watch?v=YgwKPP2ZEjI. At about 10 minutes he starts working on the actual fluid sim (before that is just basic lighting setup) and at 17:00 is where he starts setting up the glass that the water will be going into.

For the color part: I don't know about coloring particles directly - I have just been using objects as the particle (like in my screenshot above where I used spheres) and every tutorial I have seen using colored particles has also used an object as the particle. Maybe you can color a particle directly without it needing to be an object in Blender Internal, but I am not sure.
