I don´t know if this can help but as I know (same in the FSX SDK) the first three numbers are RGB (Red, Green, Blue) and the four is the alpha among in this particle (texture) If you want turn the color of your effect, as I understands, from white to gray you must try this:

Color Start=255, 255, 255, 200
Color End=155, 155, 155, 200

255 is max color where 255,0,0 is pure red, 0,255,0 pure green and so

Now, I have not remember how the alpha work, I assuming that 255 is NO alpha, which means no transparency. and 0 invisible particle... you must try which combination works better for you...

Good luck.
