The Monton-Skull colors collaboration is inspired by an ancient custom in Thailand where there is an astrological rule that assigns a color to each day of the week based on the color of the God who protects the day. For example, the God of Sunday is Surya who has the color red. These colors of the day are traditional Thai birthday colors and it is widely believed that dressing in a certain color each day will bring you good luck. The code is: Monday, yellow; Tuesday, pink; Wednesday, green; Thursday, orange; Friday, blue; Saturday, purple; Sunday, red.
