Tuesday and red are related to the planet Mars. Red is a colour of energy, life-force, grounding and power/willpower. 

Mars represents the energy and drive of a person, their courage, determination, and spontaneous impulses. It also describes your readiness for action, the way one goes about doing things as well as simple aggression, anger, and frustration. It relates to competition, domination, authority, and personal strength. It connects to a very basic, practical and material side of life. Red is a colour of abundance as well as survival and basic emotions, e.g. including loyalty and sexuality. It is also a colour of protection but in an isolated way. Also, red purifies and transforms just as fire does. 

Mars can be a highly creative or destructive force. As a destructive force, it can be misused in manipulation and over control. If not in balance, mars can bring frustration and embarrassment due to its quick and uncontrolled reactive manner. If there is agitation under the surface it can heighten frustration within and in relation to others. It is no accident that bull-fighters wear red and black! Red and mars both relate with the base chakra.  Understanding the placement in Mars in our birth chart can help us address anger and frustration, problems related to blood, matters related to our base chakra as well as help us increase our vitality and organizational skills.

People with a strong mars do well in construction, the army and make great surgeons. Wearing a little red (not too much) can enhance the positive qualities of Mars and bring grounding.
