Can pastel pink be used in a South-East kitchen?

In that horoscope the Moon is exalted and forms a strong Gaj Kesari yoga, so white does not harm them; you should use ivory. A white platform alone does not make anyone rich, nor does a platform alone make anyone a pauper: vastu is not everything and nothing is greater than karma. Vastu supports those whose karma is good, and its four controlling factors are dravya, kshetra, kaal and bhaav (substance, place, time and intention).

That is why perfect red is not used, only a light red such as lakha granite. Fire can be kept burning 24 hours in the South-East, so a red platform is acceptable there: the zone tolerates any amount of fire because the sun's rays in the South-East are not intense after 9 am, whereas hot winds (loo) come from the South.

Cold is produced from heat and a refrigerator cannot run without fire, so it can be placed in the South-East of the kitchen. Using the kitchen's own grid, it can also go in the West, and the North-West is ideal according to astrology.

Yes, the platform can be painted, but the type of paint matters, which is explained in the topic of paints, pigments and colours. Never use oil-based paint.

White is often said to be bad, but bad results from it have not been seen in practice. White is allowed in every direction; it represents the water element, yet many very prosperous homes use it, such as the white kitchen platform in the Ambani home. This advice rests on case studies rather than copied literature, which is why black, not white, is the colour named to avoid.

Yes, yellow can be used in the kitchen, for example yellow furniture.
