In Vedic astrology, every day of the week is ruled by a planet, and aligning small choices with that planet, like the colour you wear, is believed to invite its positive energy. Wednesday is ruled by Mercury (Budh), the planet of intellect, communication and business, and its colour is green. Here's why green and Wednesday go together, what Mercury represents, and how to make the most of the day.

Mercury (Budh): the ruler of Wednesday
The Hindi name for Wednesday, Budhvar, comes straight from Budh, the Sanskrit name for Mercury. The same link shows up in European languages: the French mercredi and Spanish miércoles are both named after Mercury.
Mercury is the fastest-moving planet and the closest to the Sun. In Vedic astrology it governs:
- Intelligence and learning: memory, logic, analysis and quick thinking.
- Communication: speech, writing, negotiation and wit.
- Business and trade: commerce, accounting, marketing and deal-making.
- Youthfulness and curiosity: Budh is often described as a young, playful prince among the planets.
Astrologers say that people with a strong Mercury in their chart tend to be articulate, sharp and good with numbers, while a weak or afflicted Mercury may show up as nervousness, indecision or trouble expressing oneself.
Why is green Mercury's colour?
Every planet in Vedic astrology has its own colour, gemstone and metal. For Mercury, the colour is green and the gemstone is emerald (panna). Green is the colour of new leaves, growth and freshness, qualities that mirror Mercury's quick, youthful and adaptable nature.
According to astrological tradition, wearing green on Wednesday is believed to:
- Support focus, memory and clear thinking, which is why it's popular with students.
- Help communication flow in meetings, interviews and presentations.
- Attract success in business and trade.
- Bring a sense of balance and calm to a busy midweek.
- Strengthen Mercury's influence, especially for people whose charts show a weak Mercury.
Wednesday's deities: Lord Ganesha and Lord Vishnu
Wednesday is widely dedicated to Lord Ganesha, the remover of obstacles and patron of wisdom and new beginnings. He is traditionally offered durva grass, which is green, another reason the colour fits the day. In Vedic astrology, Mercury's presiding deity is Lord Vishnu, so some devotees also honour Vishnu on Wednesdays for stability and abundance.
Who benefits most from wearing green on Wednesday?
Because Mercury rules the mind, speech and commerce, astrologers especially recommend green on Wednesdays for:
- Students preparing for exams or starting a new subject.
- Public speakers, teachers and presenters.
- Writers, journalists and content creators.
- Traders, marketers, salespeople and entrepreneurs.
- Anyone with an interview or important conversation on a Wednesday.
Simple Wednesday practices for Mercury
- Wear something green, whether it's a full outfit, a tee or a single accessory.
- Chant the Budh Beej Mantra: Om Braam Breem Broum Sah Budhaya Namah. It's traditionally recited 108 times on Wednesday.
- Keep green plants on your desk or in your workspace.
- Offer durva grass to Lord Ganesha if you follow the tradition.
- Keep dark, dull colours to a minimum. Some astrologers believe very dark shades like black dull Mercury's bright, quick energy.
Anyone considering wearing an emerald for astrological reasons is usually advised to consult an astrologer first, as gemstone recommendations depend on the individual chart.
How to wear green without overthinking it
- Olive is the easiest green to wear. It goes with black, white, beige and denim.
- Light and mint green look fresh with off-white or grey bottoms.
- Bottle green works best as a layer, like a jacket or hoodie over a plain tee.
