The colors white and yellow have special significance in Saraswati puja outfits. White is considered to be a symbol of purity, simplicity, and knowledge. It represents the purity of mind and thought that is necessary to gain knowledge and wisdom.  Yellow, on the other hand, is the color of the goddess Saraswati herself. It represents the color of enlightenment, positivity, and optimism. Wearing a white and yellow outfit during Saraswati puja is believed to invoke the blessings of the goddess, who is considered to be the embodiment of knowledge, music, art, and learning. The colors are also seen as a representation of the values that the goddess stands for, such as purity, simplicity, and positivity. It’s worth noting that the significance of these colors may vary in different regions and communities, but overall, white and yellow are considered to be auspicious colors during Saraswati puja.
