The Manroth tartan is even closer to your desogn with the yellow stripe.

The problen with decorated blue, green and black setts is that there are a lot of variations on a theme already in existance. That said, so long as your design is unique and you don't want to register it in the NTR (there's no requirement) then something similar is not a problem unless it's likely to be confused with a tartan protected by Design Registration.
