Indians generally prefer to avoid black during any auspicious occassion such as a Pooja or any festivals. Generally it is presumed that wearing the colour black reflects sadness and you are not supposed to be sad on these days. This is what we were taught since our childhood.
Interestingly, everything that we do in our culture also has a scientific reason.
Earlier, every family member would gather together for all these auspicious occassions. During those days, they did not have Air Conditioned Houses or Cross Ventilation and most importantly, all the Poojas and Rituals were completely followed unlike today. So when Havan or Poojas were performed a lot of heat was generated and the colour black absorbs all the light, therefore making a person feel more warm.
Secondly, considering the climatic conditions of our Country, it is important that we should dress up in light colours, with lighter natural fabric such as cotton. Our Ancestors, knew their science well, it is just that when the information was being passed down, instead of providing us with explanation, we were only given instructions.
The colour Black is not completely inauspicious during festivals because there are certain rituals, wherein people are required to wear the colour black.
When visiting Shani Shinganapur, a Shani Temple.
When visiting Sabarimala, Kerelites wear Black Dhoti, after they take the Vratam. The reason being Lord Ayyappa asked Lord Shani to protect his devotees from every harm and therefore in order to please Lord Shani, the devotees wear black colour travel without footwear follow brahmacharya. While, I think the scientific reason for the same is because the temple is located on the hills, it would be to protect them from the cool climate.
In Maharashtra, during Makara Sankranti, Women are usually dressed in their best Black Sarees, because as it the last day of Winter, it is presumed to be the coldest day. Makara Sankranti is a big day for married women in Maharashtra.
If the colour Black was so inauspicious for Hinduism then our Mangalsutra, which is the biggest ornament for a married woman, would not have black beads.
