Where should multi-coloured objects be kept?
Anywhere; multi-coloured items are allowed in all directions, just as you wear multi-coloured clothes. All five elements can exist within an inch of space; trouble comes only when anti-element items are used in large quantity.

From where to where does the fire element zone extend?

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 the colour of a small area in the earth element zone is changed, or an imbalancing item is kept there, does it affect the whole house?
Yes, it affects the whole house. Just as dirt in one room spreads its smell through the air to the other rooms, an imbalance in one zone spreads to the entire house.

Why does the colour of the kitchen platform matter so much?
Eye contact is greatest with the platform, since rolling, chopping and all cooking work happen on it, so its colour works on the eyes and mind. In a wrongly placed kitchen the right platform colour alone can correct about 25% of the dosh: ivory for South, South-East, South-South-East and West-South-West kitchens; light red lakha granite for South-East and South-South-East, used sparingly because red stone comes only as granite, which develops pin holes; yellow for South-West and West; and green for South-East, South-South-East, South, North-East and North.
