In Thai tradition, there is an astrological rule (which has influence from Hindu mythology) that assigns colour for each day of the week. The colour is assigned based on the colour of the God who protects the day or Navagraha. For example, the God of Sunday is Surya which has red colour. These colours of the day are the traditional Thai birthday colours. For example, King Bhumibol was born on Monday, so on his birthday throughout Thailand will be decorated with yellow colour.
| Day | Colour of the day | Planet | God of the day |
|---|---|---|---|
| Monday | Yellow | Moon | Chandra |
| Tuesday | pink | Mars | Mangala |
| Wednesday | green | Mercury | Budha |
| Thursday | orange | Jupiter | Brihaspati |
| Friday | blue | Venus | Shukra |
| Saturday | purple | Saturn | Shani |
