Fluid Color problem

[Spectra_7]

Hello.

I am having problem with few colors of the particles. Screenshot below:


In the above screenshot, below buttons selects color of fluid. I set the color of fluid from ObiEmitterDiskShape component via script.
The problem is if I select purple color, it still drops blue colored fluid like in screenshot above. Same happens when I select yellow color, but it drops in red color.

Thanks.
