The development plan allows clinker bricks in the colors "natural red, red, or reddish brown."
By the way, I meant that in the B -Plan "red, natural red, and brown" are permitted.
So, what is it now? What does the development plan actually say?
From the authority's point of view, there is no reason not to agree on the permitted colors of a clinker brick.
If you don't like them or prefer another clinker brick, that is your personal problem. Why should others adhere to the development plan, but you not?
You won't suffer any disadvantage or harm if you comply.
Besides, you are not doing yourselves any favors by wanting to build a special case. That immediately spreads a negative impression in the neighborhood—whether you understand it or not.
