We can utilize the particular vibrational influences of color to enhance our physical and mental well-being.  It’s simple and takes little time or effort to mindfully incorporate a bit of color therapy into your life. Of course, painting your walls to achieve healing benefits of color will have a profound and noticeable effect. Other subtler but more practical methods include a color breathing meditation or drinking color-infused water. Color infusions can be made by using tinted bottles or transparent filters over bottles of water. Set your water-filled container in a window for 1-3 hours and drink to your health.
