The coastal districts are generally white. Most new buildings and estates are either white or a light colour that compliments the coast dabaqa cali mahdi, pearl beach etc
The interior districts is a different story where you find every colour under the sun. Pink, green, bright yellow waa reer baadiiye.
Villa Somalia and all govt buildings such as the ministries, hospitals, banaadir HQ, national university are all white as they were pre 91 so it may be implented in the future, who knows
