Welcome to the forum.
The baseplates and magazine funnels sold on Waltherarms.com are made by Taylor Freelance and only come in blue or black but will have the Walther logo on them.
The ones sold on the Taylor Freelance and Springer Precision websites will be available in more colors but without the Walther logo.
I have the blue Taylor Freelance funnel and baseplates on my Q5 and am happy with them.
