Clothing Colors: Beliefs and Meanings for Each Day of the Week

The belief in “auspicious clothing colors” for each day is a long-standing part of Thai culture. It is rooted in traditional Thai astrology, which associates specific colors with the celestial bodies governing each day. Choosing to wear the “right” color is believed to help enhance one’s luck and attract good fortune into everyday life.

Inauspicious Colors (Colors to Avoid) for Each Day

According to Thai astrological beliefs, in addition to auspicious colors, there are also “inauspicious colors” or “kalakinee colors” that should be avoided on certain days, as they are thought to bring misfortune or block good luck.

Sunday – Avoid dark blue.

It is believed that this may cause obstacles at work and reduce clarity in decision-making.

Monday – Avoid red.

This color is thought to increase irritability, cause arguments, and lead to situations that do not go smoothly.

Tuesday – Avoid yellow and white.

These colors are believed to increase the risk of being taken advantage of, deceived, or suffering financial loss.

Wednesday – Avoid orange.

It is believed to cause miscommunication, misunderstandings, and unsuccessful negotiations.

Thursday – Avoid purple.

This color is thought to make learning difficult, reduce concentration, and cause missed opportunities.

Friday – Avoid black and dark blue.

They are believed to bring emotional heaviness, make love and friendships less smooth, and dampen one’s mood.

Saturday – Avoid green.

This is thought to lead to financial problems, loss of assets, or being cheated.

Tips for Choosing Workwear Colors by Day

When choosing what to wear to work, you can consider both the auspicious color of the day and the nature of your tasks:

• On days with important presentations, you might choose red or orange to boost confidence and presence.

• On days that require negotiation or building relationships, pink or blue can help create a softer, more approachable impression.

• On days requiring deep thinking and analysis, green or yellow may help stimulate the mind and support focus.

Things to Keep in Mind

The belief in auspicious and inauspicious colors is part of traditional Thai astrology and culture and is not supported by scientific evidence. In real life, many people have to wear uniforms or have limited freedom in choosing clothing colors.

Ultimately, the most important factor is choosing colors that make you feel confident and comfortable. Inner confidence affects your personality, communication, and performance far more than the color of your clothes—and that, in turn, has a much greater impact on success than any color chart.
