The Golden Spiral is a logarithmic spiral whose growth factor is φ, the “Golden Ratio”. This means a golden spiral gets wider by a factor of φ for every quarter turn it makes.
The Golden Ratio is a mathematical ratio that is commonly found in nature. Two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The value of the golden ratio is 1.618… and is represented by the Greek letter φ (phi).
“Phi, the Golden Ratio, can be found throughout life and the universe. The appearance of phi creates a sense of balance, harmony and beauty in the design we find in nature. Mankind has both applied this same proportion, both consciously and unconsciously, to achieve balance, harmony and beauty in art, architecture, design and composition.”.[1]
In this exercise we were asked to make three separate compositions focused around the golden ratio: one using primary colors (red, yellow, blue), another using secondary colors (purple, orange, green), and a third using complementary colors.
