Should golden yellow and white be used only in the North-East, or can the whole house use this combination?
The whole house can use it. The teacher has done a complete home interior in white and golden yellow, creating Gajkesari yoga throughout. When one colour combination is used in every direction, no dosh is counted.

Can a bedroom be made at Shikhi (E1), and why should it be white rather than red?
Yes, a bedroom at Shikhi can suit elderly people, and it should be painted white rather than the zone's red colour, as advised for people of kapha nature and for those of pitta nature whose heat rises quickly. Shikhi is highly sensitive and already hot, so red would add heat and open the third eye.

Why do some homes and businesses decline right after an expensive interior?
Because the interior changes colours, furniture directions, tiles and artefacts without regard to the owner's element and planets. Often the colours belong to the element opposite to the owner's, artefacts are combined wrongly, or harmful adhesives, lights and lead-based paints are used. One client who spent 60 to 80 lakh on an interior saw his loans turn NPA and his wife leave; his whole house had been painted in the colours of his opposite element.
As an interior designer, clients choose their own colours and I cannot check their planets; should I give a remedy or try to convince them?
Do not try to convince anyone. People mostly like the colours that match their own planets. If a client chooses an anti-element colour and their kundli allows it, never stop them; it will bring them benefit.
