In the planning process for building a new house - the sections have the following covenants on it:

"All external components of buildings and structures (including roofs, guttering, spouting, window joinery and above ground water and septic tanks) shall have exterior colours that are visually recessive and/or do not contrast with surrounding natural colours in accordance with the following colours from the British Standard (BS5252 colour range, Groups A and B with a maximum reflectivity of 40% for exterior walls and 30% for roofs)."

We are quite keen to do a black long run iron roof with as close to black board and batten exterior. When I look up the colour chart referenced above black does not feature on this specifically but meets the maximum reflectivity with around 5-6%

any thoughts on weather or not this will get blocked through council?
