In terms of bag color choices, there are several colors that are considered to be very versatile and easy to match. Firstly, black bags are classic and highly versatile, able to pair with virtually any color of clothing, whether it's a simple or elegant style. Secondly, red bags are also easy to match, despite their bright color, as they can complement both cold and warm tones of clothing well.

In addition, coffee brown and light purple are also considered versatile colors. Coffee brown is relatively soft and won't appear too dull or mature, while light purple is beautiful without being overstated, easily pairing with various styles of clothing.

Moreover, white and silver bags are also popular, adding a fresh or elegant feel and coordinating well with various clothing styles.

However, when choosing a bag color, it's important to consider one's skin tone, preferences, and daily dressing style to ensure that the selected bag truly meets one's needs and taste.
