Welcome Raiko. Good to have you here.
I don't really have a favorite color. I own two spoos, one blue and one apricot. For me, it is more about personality and form. But if I had to choose a color that I find really interesting just for color sake, I would go for the partis.
From website:
A Parti Standard Poodle is not a mismarked poodle or a Standard Poodle that likes to party poodle, although I'm sure they would enjoy a good party! They are actually Poodles that are more than one color, such a black and white, brown and white, or the rarer, lemon and white. A mismarked Poodle is usually recognized as being mostly all one solid color with just a little color somewhere else, which is usually white. In the Parti colored Poodle, the color distribution is preferably 60% white and 40% of another color.
