This study employs the traditional color wheel as foundation and assigns each of the twelve colors on the color wheel with a unique number to form ”Numeric Color Wheel”. By knowing the numeric value of a color, art beginners will be able to conclude the tone of the color as well as its complimentary color number. When mixing colors, art beginners can take any two colors' numeric numbers to form a color-mixing array by using the Numeric color wheel and then accurately predict the mixing result. Numeric Color Wheel places the color 'black' in the center of color wheel and puts the color 'white' on the outer circle of color wheel. By doing so, numeric color wheel forms polar coordinate system, allowing art beginners to master techniques such as creating hue difference or adjusting color values. Numeric Color System redefines the color wheel by skillfully combine color tones and values together. The tone of the color changes according to numeric color wheel's angle (ø) while the value of the color varies according to wheel's radial position (r). Chroma is determined by the vertical axis in the color wheel plane, and it forms a cylindrical coordinate system along with tones and values. This concept presents a new color definition in art education field.
