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.

Can these planet artifacts be used even when the birth chart shows no defect?
Yes. Without a dosh they simply add energy. Nobody would refuse if God offered an exalted Jupiter, Mars or Saturn in their chart, and decorating with the items that represent such planets raises energy in the same way. Energy never becomes so much that it causes harm; how the gain is used is the person's own responsibility.
How can I choose the colour that awakens my fortune for my bedroom if I have no horoscope or cannot read it?
Take a colour catalogue and turn its pages with your own eyes: the colours you are drawn to are the ones that awaken your fortune. Use that colour along with the colour of the zone you sleep in, and if possible match it with your horoscope; it usually matches. Sleeping steadily for eight hours in that colour lets its planet act on the whole body.
How do we choose a direction when no planet in the chart is exalted and several planets sit in one direction?
First choose the direction of exalted planets. If none are exalted, go towards the direction where the benefic planets sit: Venus, Mercury, Moon and Jupiter are benefic, while Rahu, Ketu, Saturn, Sun and Mars are malefic. Then use the interior items, seed mantras, artifacts, statues, trees, colours and symbols, to strengthen the planets that are not exalted.
If Mars as the 10th lord (karmesh) is debilitated, should red be avoided in the logo?
Yes. A debilitated karmesh does not support you, so avoid its colour in the business and the logo, and take the colour of the 11th lord (labhesh) instead.
If a planet's colour (for example Mercury's) cannot be used in its zone, can the colours of its friends or of the zone element's friends be used?
First see what Mercury is in your chart (exalted, bhagyesh or lagnesh, which supports health) and where it sits. If its own colour cannot be used in that zone, use the colours of Mercury's friends, and the colours of the friends of that zone's element must also be taken.
If one family member has a planet exalted and another has it debilitated, should that planet's items be kept in the interior?
Decide room by room. In your own bedroom use the materials of your exalted planet and not of your debilitated one; your daughter's bedroom is designed from her kundli. The house facing and common areas such as the drawing room and kitchen are decided from the grih swami's kundli. Many people make the master bedroom in the South-West by default, which is wrong when Rahu is debilitated: such people suffered there and got very good results after moving to another direction.
