Dear Mr. Bureaucrat of the road authority
I just write to say, here it is. A new piece adapted to your approved colour-code. However I am not totally happy with the contrast. It certainly does not comply with the new “design for all” standards, which I would have thought you had to conform to. Still at the same time the lack in contrast gives it an interesting blurred quality, but alas less noticeable. I guess you win some and lose some. So even if it is in accordance with regulations, I cannot promise I will stick to this nuance for future projects. Anyway, I will use this opportunity to once again thank you for pointing me in the right direction regarding acceptable shades of grey.
With expectation that this will not be removed, sincerely,
the street artist
