Who is the originator (janak) of interior vastu?
Adi Brahma (Adi Prabhu) gave each son a different knowledge: Bharat received arthashastra, Bahubali kaam neeti and Ayurveda, Vrishabhsen gandharva shastra (music and instruments), and Anant Vijay all the arts of painting, colour, brushwork and artefacts. Anant Vijay is therefore the source of interior knowledge, which he spread further, and Vishwakarma received the knowledge of vastu.

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.
